Rubber Stoppers for Blood Collection Tube are critical components in blood collection tubes, playing a pivotal role in maintaining sample integrity and ensuring the accuracy of diagnostic tests. These stoppers are designed with specific characteristics that contribute to their functionality, compatibility with various blood collection methods, and preservation of blood samples during transportation and analysis.

Rubber stoppers used in blood collection tubes are typically made from synthetic rubber compounds that comply with regulatory standards for biocompatibility and medical device safety. The materials used ensure that the rubber stoppers do not interact chemically with blood components or additives used in blood collection tubes, thereby preventing contamination or alteration of blood samples. Biocompatibility is crucial to maintaining the stability of blood samples and ensuring accurate test results in clinical diagnostics.

One of the primary functions of rubber stoppers is to provide a secure seal when inserted into blood collection tubes. The stoppers are designed to create an airtight and leak-resistant closure that prevents the escape of blood or additives from the tube during handling, transportation, and centrifugation processes. This secure seal minimizes the risk of sample contamination and ensures the integrity of blood samples until they are analyzed in the laboratory.

Rubber stoppers must be compatible with various additives and anticoagulants used in blood collection tubes to maintain their efficacy and stability. These additives, such as EDTA (Ethylenediaminetetraacetic acid), citrate, or heparin, are essential for preserving blood samples and preventing clotting during storage and transport. The composition of rubber stoppers ensures that they do not react with or absorb these additives, thereby preserving their functionality and effectiveness throughout the blood collection process.
