Clot Activator Plastic Blood Collection Tube

Introduction
A clot activator plastic blood collection tube is a medical consumable used for blood collection and short-term storage in clinical and laboratory settings. These tubes are made from medical-grade plastic and pre-coated with a clot activator, which helps accelerate blood coagulation while maintaining sample stability and integrity.
In routine practice, clot activator plastic blood collection tubes are widely used for complete blood count tests, biochemical analysis, and other laboratory examinations. Their ease of use, fast clotting performance, and stable storage characteristics make them suitable for both routine testing and emergency diagnostics.
Key Features
- Smooth inner wall that allows fibrin clots and cellular debris to settle easily
- Pre-added clot activator to speed up the coagulation process
- Helps maintain platelet count and partial functional activity
- Suitable for blood collection, mixing, cell separation, and short-term storage
- Samples can be preserved for 5–7 days under proper conditions
Function
The primary function of a clot activator plastic blood collection tube is to promote rapid blood clotting and reduce sample preparation time. This is particularly useful for tests that require quick turnaround, such as emergency and routine biochemical analysis.
Working Principle
The working principle is based on the coagulation environment created by the interaction between the clot activator and the inert plastic surface. Blood coagulates quickly, forming a stable clot at the bottom of the tube, while platelet integrity is largely preserved.
How to Use
1. Open the package and prepare the tube according to instructions.
2. Add the required buffer solution and gently mix without vigorous shaking.
3. Slowly invert the tube several times to ensure proper contact between blood and the clot activator.
4. Proceed with centrifugation or analysis following laboratory protocols.
Precautions
- Control ambient temperature during collection and storage
- Collect an accurate blood volume
- Avoid excessive shaking after collection
- Maintain stable centrifugation speed
- Store samples away from strong light, vibration, and contamination
Summary and Recommendation
Due to fast clotting performance, ease of handling, and wide applicability, clot activator plastic blood collection tubes have become standard consumables in clinical laboratories. Selecting qualified products and following standardized procedures can significantly improve testing efficiency and result reliability.
