What Are PRP Tubes?

PRP tubes (platelet-rich plasma collection tubes) are sterile, single-use blood collection tubes designed to separate concentrated platelets and growth factors from whole blood during centrifugation. Each tube combines a medical-grade anticoagulant — typically ACD-A, sodium citrate, or sodium heparin — with a separation gel that forms a stable density barrier between the platelet-rich plasma layer and red blood cells. The result is a consistent, reproducible platelet concentrate that clinics use in aesthetic, dermatologic and orthopedic protocols.

If you are asking what is a PRP tube or searching for a tube for PRP that fits your clinic's workflow, this guide walks through every decision point: anticoagulants, gel technology, sizes, materials and application-based selection. VivaPRP is a manufacturer-direct supplier of CE-certified PRP tubes in 8ml, 10ml, 12ml and 15ml sizes, engineered in a controlled sterile facility and available as single tubes, clinic boxes and bulk wholesale quantities. The product range spans four separation-gel configurations — ACD+Gel, Sodium Heparin+Gel, ACD+GEL+BIOTIN and GFC — covering standard, heparin, hair-focused and growth-factor-concentrate protocols.

PRP tubes are not the same as a complete PRP kit — kits bundle tubes with needles, syringes and transfer components — and they differ from PRF tubes, which use no anticoagulant so blood can clot naturally. This page focuses on PRP tubes; see our guide to PRP tube types and components for a deeper technical breakdown.

How PRP Tubes Work: The Separation Principle

When whole blood is drawn into a PRP tube and centrifuged, three layers form:

Platelet-poor plasma (PPP) — the top layer
Buffy coat / platelet-rich layer — the middle layer, where platelets concentrate
Red blood cells — the bottom layer, trapped below the gel

The anticoagulant inside the tube keeps blood from clotting during processing, while the separation gel sits between the plasma and red-cell fractions after centrifugation, letting you draw off the platelet-rich portion cleanly. Platelets carry growth factors — including PDGF, VEGF and TGF-β — that are the active components used in clinical protocols.

The choice of anticoagulant and gel directly affects platelet recovery and protocol consistency, which is why tube selection matters more than most clinics realize. For a practical comparison, see PRP tube anticoagulants: ACD-A vs sodium citrate vs heparin.

Anticoagulants: ACD-A vs Sodium Citrate vs Heparin

The anticoagulant is the single most important component of a PRP tube. It determines how long blood stays fluid during processing and how well platelets remain intact.

Anticoagulant	How it works	Best suited for
ACD-A (Anticoagulant Citrate Dextrose Solution A, USP)	Chelates calcium ions to prevent clotting; contains 2.13% free citrate ion	Standard PRP preparation; ACD-A is the only anticoagulant the U.S. FDA has approved for use in autologous PRP systems
Sodium Citrate	Chelates calcium ions; simpler formulation	Budget-friendly PRP protocols; widely used in manual processing
Sodium Heparin	Binds thrombin to inhibit clotting	Protocols requiring a non-citrate option; heparinized tubes are also used in some orthopedic applications

Two practical points worth noting:

ACD vs sodium citrate in PRP tubes: both work by calcium chelation, but ACD-A is formulated specifically for blood-component separation and is the anticoagulant named in FDA-cleared autologous PRP system documentation. Many published protocols specify ACD-A for consistent platelet recovery.
Activation: some protocols add calcium chloride (CaCl₂) or a separate activator after PRP extraction to trigger platelet degranulation. The anticoagulant prevents clotting during processing; activation happens after separation, outside the tube.

We offer PRP tubes with ACD-A and gel separator and sodium heparin PRP tubes. If you are deciding between them, our article on choosing the right PRP tube anticoagulant breaks down the differences in platelet yield and protocol fit.

Gel Separator Technology: Why It Matters

A PRP tube with separating gel uses a thixotropic gel that moves during centrifugation and forms a physical barrier between plasma and red cells after the spin. This delivers three clinical benefits:

Cleaner separation — the gel prevents red-cell re-mixing when the tube is handled after centrifugation
Higher, more consistent platelet recovery — the platelet layer is captured in a defined zone above the gel
Simpler protocol — no pipetting through red-cell contamination

PRP gel tubes are the industry standard for reproducible results. Tubes without gel require careful timing and technique to avoid disturbing the fractions, which introduces variability into your results. For clinics running high patient volumes, the consistency of a prp gel tube is worth the small cost difference.

VivaPRP's PRP gel separator tubes are available in ACD-A, sodium heparin and activator configurations. See how the gel separator in PRP tubes works for the technical detail behind the density barrier.

PRP Tube Sizes & Materials: 8ml to 15ml

PRP tube size determines how much whole blood you draw and how much PRP you can produce per tube. All VivaPRP tubes share a standard 16mm diameter, with length varying by volume.

Volume	Dimensions	Typical whole-blood draw	Typical use
8ml	16 × 100 mm	~8ml	Microneedling, small facial areas
10ml	16 × 100 mm	~10ml	Facial aesthetics, hair restoration
12ml	16 × 120 mm	~12ml	General clinical use, larger procedure areas
15ml	16 × 120 mm	~15ml	Orthopedic and joint protocols, high-volume applications

Materials: PRP tubes are manufactured in PET (polymer, unbreakable in routine use, the standard choice) or glass (traditional, more fragile — handle with care). PET tubes are preferred by most clinics for safety and logistics, while glass remains an option for specific protocols.

Size availability varies by type: ACD+Gel and ACD+GEL+BIOTIN are produced in all four volumes (8–15ml); Sodium Heparin+Gel in 8ml and 10ml; GFC in 10ml.

A common question is which size to start with: most aesthetic clinics keep 10ml tubes as their daily driver, with 12–15ml tubes reserved for larger-volume applications. Bulk buyers can order 50-piece boxes of PRP tubes or 10ml ACD gel tubes in clinic packs. Our guide to PRP tube sizes and materials covers dimension compatibility with common centrifuges.

PRP Tube Specification Table (8 / 10 / 12 / 15 ml)

Before comparing brands, fix the specification you actually need. The table below is the VivaPRP tube range as it is configured today — read it top to bottom and note the three lines that decide whether a tube fits your protocol: additive, separation technology and rotor compatibility.

Specification	VivaPRP tube range
Available volumes	8 ml / 10 ml / 12 ml / 15 ml
Additive options	ACD-A (Acid Citrate Dextrose Solution A) · Sodium Heparin + Gel · GFC gel · Activator gel
Separation technology	Density-gradient gel separator
Tube material	Medical-grade PET
Sterilisation	Individually sterile-packaged, single-use — method and cycle recorded per lot
Shelf life	24 months unopened
Storage	4–25 °C, protected from light
Packaging	50 tubes per box, or 500-piece bulk packs
Recommended centrifugation	1,500 rpm × 8 minutes
Mixing	Invert gently 8–10 times before centrifuging
Collection to separated plasma	Approximately 15 minutes
Traceability	Lot number (LOT) recorded per unit
Centrifuge compatibility	TD4C desktop centrifuge (8 × 10/15 ml rotor) or an equivalent low-speed benchtop centrifuge

How to read this table

Three lines carry the decision. Additive determines whether the tube matches a protocol you have already validated. Separation technology determines whether you can aspirate the plasma layer without a second spin. Centrifuge compatibility determines whether the tube physically seats in the rotor you own — a tube that does not fit is not a tube, it is inventory.

One line is deliberately narrow: the sterilisation row names the packaging and points to the cycle record on the lot documentation, rather than assuming a single method across every product. Sterilisation cycles differ by product family and by production run, so the authoritative figure is always the one printed on the lot paperwork that ships with your order — not a marketing line on a page.

PRP Tube Types Overview

VivaPRP manufactures four PRP tube configurations, all featuring a separation gel. Each configuration pairs an anticoagulant system with an optional additive, so the right choice comes down to your protocol and clinical workflow:

PRP Type	Anticoagulant	Gel	Additive	Available volumes
ACD+Gel	ACD-A	Separation gel	—	8ml · 10ml · 12ml · 15ml
Sodium Heparin+Gel	Sodium heparin	Separation gel	—	8ml · 10ml
ACD+GEL+BIOTIN	ACD-A	Separation gel	Biotin (vitamin B7)	8ml · 10ml · 12ml · 15ml
GFC (Growth Factor Concentrate)	—	Optimized concentrate gel	—	10ml

ACD+Gel is the clinical standard — ACD-A anticoagulation with a separation gel, spanning the full 8–15ml range for facial, hair and general aesthetic protocols.
Sodium Heparin+Gel covers non-citrate protocols, commonly used in orthopedic workflows, available in 8ml and 10ml.
ACD+GEL+BIOTIN adds biotin (vitamin B7) to the standard ACD gel system. The biotin is released into the plasma fraction during centrifugation, giving hair restoration protocols a hair-focused formulation in the same familiar tube format.
GFC uses an optimized gel to concentrate growth factors, available in 10ml for advanced regenerative protocols.

How to Choose PRP Tubes: Selection by Application

The right PRP tube depends on the procedure, the volume you need, and your protocol's anticoagulant preference. Use this decision framework:

Microneedling & facial aesthetics

Recommended: 8–10ml ACD + gel tubes
Why: smaller volumes match facial procedure areas; the gel keeps separation clean during multi-site injections
Related reading: choosing PRP tubes for microneedling

Hair restoration

Recommended: 10ml ACD+Gel, or ACD+GEL+BIOTIN for hair-focused workflows
Why: hair protocols typically need consistent volumes across multiple injection sites; the biotin (vitamin B7) additive is released into the plasma fraction during centrifugation
Related reading: PRP tubes for hair restoration

Facial rejuvenation & skin quality

Recommended: 10ml ACD + gel, or GFC tubes for growth-factor-rich concentrate
Why: GFC maximizes growth-factor concentration for skin-quality protocols
Related reading: PRP tubes for facial rejuvenation

Orthopedic & joint applications

Recommended: 12–15ml tubes; heparin or ACD depending on protocol
Why: larger blood volumes are typically required for joint-volume injections
Related reading: PRP tubes for orthopedic applications

Best PRP tubes is ultimately a protocol question — the "best" option is the tube that matches your centrifuge, your anticoagulant preference and your procedure volume. Start with 10ml ACD + gel as your default and add sizes as your case mix grows.

Which Tube Should You Choose? Model-by-Model

Abstract selection advice is not much use at the point of ordering. Below is each configuration we stock, written as the situation it solves.

ACD-A + gel, 8 ml — choose this if

Your cases are small-area and single-site, and you want a tube that fills quickly with a smaller draw. The 8 ml format is the tightest option in the citrate range and seats in both the 8 × 10–15 ml rotor and the 12 × 5–7 ml rotor.

ACD-A + gel, 10 ml — choose this if

You want one volume that covers most of what a general aesthetic practice runs, and you would rather stock a single size than three. This is the volume most clinics settle on because it seats in every rotor configuration we list.

ACD-A + gel, 12 ml — choose this if

Your work is scalp and mid-volume, and you are repeatedly short on plasma from a 10 ml draw. Moving up one step preserves the same protocol timing while raising the volume available per tube.

ACD-A + gel, 15 ml — choose this if

You are covering larger surface areas or more than one site in a session, and a single 10 ml draw keeps leaving you with a marginal yield.

Sodium heparin + gel, 8 ml and 10 ml — choose this if

Your written protocol is heparin-based. This is a different anticoagulant system from the citrate range, not a substitute for it — picking this tube because stock was short means re-validating your run.

GFC gel tube, 10 ml — choose this if

You prepare growth factor concentrate as a separate workflow. GFC is its own system with its own processing logic, so it should not be planned around PRP tube timings.

Activator gel tube, 10 ml — choose this if

Your process activates platelets after centrifugation and recovers a cell-free serum. Treat the activation step as part of the protocol rather than an optional finish.

PRF tubes — choose this if

Your workflow is PRF rather than PRP. PRF tubes are a separate family with their own design requirements; they are not a PRP tube used differently. See the PRF tubes guide before ordering across families.

Still undecided between two volumes?

Buy one box of the smaller format and one of the larger, run each through your existing protocol once, and compare the plasma volume you actually recover. That single comparison answers the question more reliably than any table, and it costs one box rather than a re-validated protocol.

Single Spin vs Double Spin Protocols

PRP can be prepared with a single low-speed centrifugation or a two-step double-spin protocol:

Single spin (typical: ~3,000 rpm, 8–12 minutes, low speed): faster workflow, good platelet concentration for most aesthetic procedures
Double spin (first spin to separate, second spin to concentrate): higher platelet concentration for protocols that need it, longer processing time

Your tube choice interacts with both: gel-separator tubes make single-spin protocols significantly more consistent, because the gel locks the fractions in place without a second spin. Tube size also matters — larger volumes need a centrifuge with sufficient capacity.

We carry desktop low-speed PRP centrifuges and a full PRP centrifuge collection sized for 8–15ml tubes. For clinics starting out, our article on PRP starter kits with centrifuge covers complete setup options.

Quality, Sterility & Certification: What to Look For

When evaluating PRP tubes — whether you are comparing best blood collection tubes for PRP or checking a new supplier — verify these six quality signals:

CE-marked: the tube carries the CE mark as a medical device under the EU regulatory framework — the mark is the verifiable regulatory signal.
Sterility: confirm the sterilization method. VivaPRP tubes are gamma-irradiated (STERILE R) — terminal sterilization with a validated dose, suitable for single-use medical devices.
Shelf life: look for a stated expiry — VivaPRP PRP tubes carry a 24-month shelf life from manufacture.
Batch traceability: every tube label carries a LOT number and expiry date, so each batch is traceable to its manufacturing and sterilization record.
Single-use, pyrogen-free design: the tube is intended for one draw only, with validated materials that do not introduce pyrogens.
ISO 13485 manufacturing — VivaPRP's tubes are produced under an ISO 13485 quality management system, the international standard for medical-device manufacturing, covering production, QC and sterilization.

On the anticoagulant point, note the scope of regulatory language: ACD-A is the only anticoagulant the U.S. FDA has approved for use in autologous PRP systems — this refers to the anticoagulant solution itself, not to any individual tube or kit as a whole system. For the full picture on device regulation, read FDA vs CE marking for PRP tubes and kits and our CE certification guide for medical products.

To verify a supplier's claims independently, our checklist on how to verify a PRP manufacturer's certification walks through the documents you should request — sterilization certificates, batch records and device registration.

Sourcing PRP Tubes: Wholesale, Bulk & OEM

VivaPRP is a manufacturer-direct supplier — we engineer, produce and ship PRP tubes from our own facility, which is what clinics and distributors look for when they search for a prp tube supplier or compare prp tubes price across manufacturers.

What you can order:

Option	Details
Single tubes / clinic boxes	8–15ml, ACD, heparin, GFC and multi-config
Bulk & wholesale	50-piece boxes and 500-piece bulk packs with volume pricing — see wholesale PRP tubes and bulk PRP tubes (500 pcs)
OEM / private label	Your brand, logo and label on our tubes — full OEM & private label service
Contract packaging	Custom box quantities and clinic-specific pack configurations

Buying directly from the manufacturer means: no intermediary markup, direct batch traceability, and a single point of contact for documentation. Clinics buying in volume typically start with our wholesale page to review MOQ and tiered pricing; our supplier checklist for sourcing PRP tubes covers the questions to ask any manufacturer.

Storage, Handling & Shelf Life

PRP tubes are sterile single-use devices and should be handled accordingly:

Shelf life: 24 months from the date of manufacture (check the EXP date on each label)
Storage: keep boxes in a cool, dry place at room temperature, away from direct sunlight and moisture
Do not freeze — freezing can damage the anticoagulant formulation and tube integrity
Inspect before use: confirm the tube is sealed, the gel is intact and the expiry date has not passed
Single use: use each tube for one draw and dispose of it according to your facility's biohazard procedures

Why the production date matters

The production date is one of the first details clinicians check on a PRP tube, and it matters for three product-related reasons:

Vacuum strength. PRP tubes are evacuated collection tubes — the draw volume is set by the vacuum inside. Over time the vacuum can decline, so an aged or expired tube risks drawing below the target volume. Underfill changes the blood-to-anticoagulant ratio, which can affect platelet recovery and protocol consistency.
Anticoagulant and gel stability. The ACD-A or heparin solution and the separation gel are validated for the full labelled shelf life; performance beyond that window cannot be guaranteed.
Sterile barrier and seal integrity. Gamma-sterilized single-use tubes rely on packaging integrity, which is guaranteed only until the expiry date.

VivaPRP prints the production date and batch (LOT) plus expiry (EXP) on every tube, rotates stock first-in-first-out, and can confirm remaining shelf life on bulk and wholesale orders before you commit. See our guide to reading a PRP tube label for what to check before each draw.

A full clinic-facing guide — including what happens if tubes are stored incorrectly and how to rotate stock — is in PRP tube storage, shelf life & handling.

Troubleshooting: Gel Inversion, Haemolysis and Incomplete Clotting

Most tube failures in a PRP workflow are handling problems, not product problems — and most of them are visible before you open the second box. Work down this table from the symptom.

Symptom	What usually causes it	What to check first
Gel barrier does not form cleanly, or sits above the red cell layer	Spin parameters outside the validated range, or a tube spun at different speed or time than the rest of the batch	Confirm 1,500 rpm × 8 minutes on the centrifuge display, not on the protocol sheet; confirm the rotor was balanced
Barrier forms but the plasma layer is hard to separate	Under-filled tube, or the sample sat before centrifuging	The fill line — a partial draw spins differently from a full one; and the time between draw and spin
Red-tinged plasma	Haemolysis during collection or handling	Needle gauge and draw technique, excessive negative pressure, vigorous mixing, or shaking during transport
Incomplete clotting in an activating tube	The activation step was shortened, or ambient temperature was low	The full activation step and the room temperature the tubes were held at, before changing anything else
Low plasma volume even though the draw looked correct	Volume selected is simply small for the application	Whether the next volume up removes the problem — this is the most common and the most easily solved cause
Tube re-spun to "improve" separation	Second spin on a gel separator tube after the barrier has set	Do not re-spin. If separation was inadequate, fix the first spin parameters instead

The four variables worth writing down

If you are troubleshooting more than one bad batch, record these four for every run: draw volume, time from draw to spin, exact centrifuge setting, and room temperature. Almost every "bad batch" traces back to one of them drifting, and none of them are visible on the box.

FAQ

1. What is a PRP tube used for?

A PRP tube is a sterile, single-use blood collection tube used to prepare platelet-rich plasma. Blood drawn into the tube is centrifuged, and the anticoagulant plus separation gel isolate the platelet-rich fraction for use in aesthetic, dermatologic and orthopedic protocols.

2. What is the difference between ACD-A and sodium citrate in PRP tubes?

Both are anticoagulants that work by chelating calcium, but ACD-A (Solution A, USP, 2.13% free citrate ion) is formulated for blood-component separation and is the only anticoagulant the U.S. FDA has approved for use in autologous PRP systems. Sodium citrate is a simpler citrate formulation used in budget-friendly protocols.

3. What color tube is used for PRP?

PRP tubes are not standardized to a single cap color across manufacturers. The reliable identifiers are the label, the anticoagulant printed on the tube, and the CE mark — always verify these rather than relying on cap color alone.

4. Can I use EDTA or SST tubes for PRP?

Standard EDTA tubes are not appropriate for PRP — EDTA damages platelet membranes and interferes with activation. Serum separator (SST) tubes are designed for serum chemistry, not PRP preparation. Use tubes specifically manufactured and labeled for PRP, such as our ACD gel tubes.

5. What size PRP tube should I use?

8–10ml tubes suit facial aesthetics and microneedling; 12–15ml tubes suit larger procedure areas and orthopedic protocols. Most clinics standardize on 10ml.

6. How long do PRP tubes last?

VivaPRP PRP tubes have a 24-month shelf life from manufacture, with LOT and expiry printed on each label.

7. Are VivaPRP PRP tubes CE-marked and sterile?

Yes — all VivaPRP PRP tubes are CE-marked medical devices, gamma-sterilized (STERILE R), single-use and pyrogen-free.

8. Can I order PRP tubes in bulk or with my own label?

Yes — we offer bulk and wholesale pricing (wholesale page) as well as OEM and private-label manufacturing (OEM service).

9. Do you offer PRP tubes with biotin?

Yes — our ACD + Gel + Biotin configuration is designed for hair restoration workflows, combining ACD-A, separation gel and biotin (vitamin B7).

10. Why does the production date of PRP tubes matter?

The production date determines how much of the 24-month shelf life remains, and freshness is tied to tube performance — vacuum draw strength, anticoagulant and gel stability are validated for the labelled shelf life. VivaPRP prints production (LOT) and expiry (EXP) dates on every tube and can confirm remaining shelf life on bulk orders.

11. Is "medical PRP tube" different from a "PRP tube"?

In supplier catalogues and clinical documentation, the terms "medical PRP tube" and "PRP tube" refer to the same device class: sterile, single-use blood collection tubes manufactured and CE-marked for PRP preparation, with a medical-grade anticoagulant (ACD-A, sodium heparin or sodium citrate) and a separation gel. The "medical" prefix is a labelling convention used by manufacturers to distinguish these devices from standard laboratory or IVD blood collection tubes. When you compare options — whether the listing says prp tube, medical PRP tube, or tube for PRP — verify the same signals: CE marking as a medical device, the anticoagulant printed on the label, sterility, and ISO 13485 manufacturing.
