Understanding Rubber Stopper Vacuum Blood Test Tubes

Rubber stopper vacuum blood test tubes are essential components in the medical field, designed for the collection and preservation of blood samples for diagnostic purposes. These tubes, equipped with a rubber stopper, create a vacuum seal that ensures the integrity of the blood sample from the moment of collection to analysis.

Types and Applications

There are various types of blood collection tubes, each identifiable by the color of the rubber stopper, which indicates the additive inside. For instance, tubes with lavender stoppers contain EDTA and are used for Complete Blood Count (CBC) tests. Tubes with green stoppers, typically used for a Complete Metabolic Panel (CMP), contain sodium heparin as an anticoagulant. The color-coded system simplifies the identification process, aiding healthcare professionals in selecting the appropriate tube for each test.

Features and Specifications

Each rubber stopper vacuum blood test tube is designed with specific features to cater to different diagnostic requirements. The rubber stoppers not only maintain a vacuum but also prevent contamination and leakage. The materials used in these tubes are carefully selected to be compatible with blood samples and the chemicals within, ensuring that the blood's properties remain unchanged until analysis.

Materials and Advantages

The materials used in vacuum blood collection tubes include glass or plastic for the tube itself, and a specially formulated rubber for the stopper. These materials are chosen for their durability and non-reactivity with blood samples. The advantage of using vacuum tubes is the precision in blood-to-additive ratios, which is crucial for accurate test results.

Selection and Usage

When selecting a blood sample tube, it is important to consider the type of test to be conducted. Each tube's specifications, such as the type of additive and the volume of blood it can hold, are tailored to meet the requirements of specific analyses. Proper selection ensures the reliability of test outcomes.
