Evacuated Blood Sample Centrifuge Tubes with Hemogard Closure for Sterility

Product Description

The design and material selection of these containers are all aimed at ensuring the stability and integrity of the samples. Sample tubes play a vital role in clinical diagnostic testing, biomedical research, and drug clinical trials. They not only protect samples from the external environment, but also prevent cross-contamination between samples. In order to better understand the specific applications and types of sample tubes, the following will discuss their types and usage scenarios in detail:

Classification by use

Serological test sample tubes: The red-top blood collection tubes are used for serological tests, such as biochemical tests and immunological tests. These blood collection tubes have no additives, and the test samples are obtained by allowing the blood to coagulate and separating the serum.

Whole blood test sample tubes: The green-top blood collection tubes contain heparin anticoagulants, which are mainly used for tests that require whole blood or plasma samples, such as electrolyte tests and emergency biochemical tests.

Blood pathology test sample tubes: Purple or pink-top blood collection tubes contain EDTA anticoagulants, which are mainly used for blood cell counts, blood typing, and blood sugar tests.

Coagulation function test sample tubes: The blue-top blood collection tubes are added with 3.2% or 3.8% sodium citrate anticoagulants, which are mainly used for thrombin time, partial thromboplastin time, and fibrinogen determination
