With advanced separation technology and plasma preservation capabilities, this tube supports a wide range of diagnostic applications and enhances accuracy in clinical decision-making. As global healthcare systems continue prioritizing quality and safety, selecting the right blood collection solution becomes more important than ever.


What Is a Pink Cap PPT Vacuum Blood Collection Tube?

A pink cap PPT vacuum blood collection tube is a sterile medical consumable used to collect venous blood for serum separation and molecular diagnostic testing. PPT stands for Plasma Preparation Tube, which contains a specialized separation gel and additives that facilitate rapid serum extraction after centrifugation.

Key elements that define the pink cap PPT vacuum blood collection tube include:

  • Pink cap color coding, indicating specific laboratory use

  • Vacuum pre-set pressure for controlled blood draw volume

  • Separation gel ensuring clear serum isolation

  • Sterile interior to maintain sample purity

  • Leak-proof and break-resistant tube design

  • High-quality PET or glass materials

In clinical workflows, the pink cap PPT vacuum blood collection tube helps automate and standardize blood testing procedures, significantly reducing manual serum transfer and human handling errors.


Primary Functions and Features of the Pink Cap PPT Vacuum Blood Collection Tube

✔ Consistent Serum Separation

The integrated separation gel forms a physical barrier between blood cells and serum after centrifugation. This prevents cellular components from interfering with biochemical assays and provides long-lasting serum stability.

✔ Prevents Cross-Contamination

The sterile inner surface of the pink cap PPT vacuum blood collection tube reduces contamination risks during blood draw and specimen processing, ensuring more accurate diagnostic results.

✔ Supports Molecular and Immunological Testing

This tube is compatible with high-precision testing methods, including:

  • ELISA and immunoassays

  • Infectious disease screening

  • DNA/RNA analysis

  • Hormone and metabolic profiling

✔ Longer Serum Preservation

By separating plasma or serum effectively, the tube helps prolong sample stability, reducing degradation and avoiding repeated venipuncture for patients.

✔ Comfortable, Safe Blood Collection Experience

Smooth-flow vacuum ensures minimal hemolysis and patient discomfort, enabling fast, efficient specimen handling.
