Plasma Separator Tubes are essential tools in modern medical diagnostics and research. These tubes are specifically designed to separate plasma from whole blood, enabling accurate analysis and testing. In this blog, we will delve into the intricacies of plasma separator tubes, their applications, benefits, and how they contribute to advancements in medical science. Whether you’re a medical professional, researcher, or simply curious about medical technology, this comprehensive guide will provide you with valuable insights.

What is a Plasma Separator Tube?

A Plasma Separator Tube (PST) is a type of blood collection tube designed to separate plasma from whole blood. Plasma is the liquid portion of your blood, carrying essential proteins, electrolytes, hormones, and nutrients.

Unlike regular blood collection tubes, a PST contains a special gel separator at the bottom. When the tube undergoes centrifugation, the gel shifts between the plasma and the blood cells, creating a barrier that maintains their separation. This makes it easier to collect plasma for testing without contamination from red blood cells or clotting factors.

What Exactly is a Plasma Separator Tube?

A plasma separator tube serves as a vacuum blood collection container coated with anticoagulants and a specialized density gradient gel. When you draw blood into the tube, the anticoagulant prevents clotting. After centrifugation, the gel creates a physical barrier between the plasma and the blood cells.

Features of Plasma Separator Tubes:

• Gel Barrier: Positioned between plasma and blood cells post-centrifugation, this gel prevents cellular contamination.
• Anticoagulants: Usually coated with substances like lithium heparin to maintain plasma in a fluid state.
• Vacuum System: Designed to draw a precise volume of blood automatically.

How Plasma Separator Tubes Work

The process of plasma separation involves several steps:

1. Blood Collection: A healthcare professional draws blood from a patient using a sterile needle and collects it directly into the plasma separator tube.
2. Mixing with Anticoagulant: The tube contains an anticoagulant, such as EDTA, heparin, or sodium citrate, which prevents blood clotting.
3. Centrifugation: The technician places the tube in a centrifuge and spins it at high speeds.
4. The centrifugal force separates the blood into distinct layers based on density.
5. Gel Separation: A gel barrier within the tube forms between the plasma and the cellular components, ensuring clear separation.
6. Plasma Extraction: After centrifugation, the plasma layer is easily accessible for further analysis or storage.

This design ensures that the plasma sample is stable, pure, and ready for analysis.

Components and Materials of Plasma Separator Tubes

The typical plasma separator tube consists of the following components:

1. Tube Material: Usually made of high-quality plastic or glass, ensuring sample stability and compatibility with testing machines.
2. Anticoagulant Additive: Lithium heparin is the most common, stopping blood from clotting.
3. Separation Gel: A synthetic, thixotropic polymer with a density between plasma and blood cells (~1.06 g/mL) that moves during centrifugation.
4. Vacuum Seal and Labeling: Standardized sizing and vacuum to control blood volume drawn for each test.

FAQs

What is the main difference between plasma and serum tubes?
Plasma tubes contain anticoagulants to prevent clotting, while serum tubes allow blood to clot before plasma removal. Plasma tubes provide plasma, while serum tubes provide serum. More details are available at Difference Between Serum and Plasma Tubes.

Can plasma separator tubes be used for all blood tests?
No. Some tests require serum or whole blood. Plasma tubes are preferred for tests that require plasma with minimal cellular contamination.

Why is the gel barrier important?
The gel barrier isolates plasma from cells after centrifugation, preventing contamination and preserving plasma integrity for accurate testing.

How long can plasma stay stable in a separator tube?
Generally, plasma is stable for 24 hours at room temperature.

Where can I find high-quality plasma separator tubes?
Siny Medical offers a wide range of certified plasma separator tubes suitable for research and clinical use at Siny Medical Blood Collection Tubes.
