Medical rubber stoppers are used to seal blood collection tubes. They are made of butyl rubber, which is a mix of 100 parts brominated butyl rubber and 10 parts titanium dioxide. They also contain 1 part carbon black and four parts light or active magnesium oxide. This mixture helps in preventing premature loss of vacuum in the tube, thus preventing leakage.
These stoppers come in various sizes and can be used for a variety of applications. For example, a 13mm rubber stopper is commonly used for blood collection. This size fits easily into laboratory glassware and test tubes. Moreover, they come in different types of synthetic rubber. One-hole rubber stoppers are common in the laboratory, and can be obtained from a rubber stopper manufacturer.
Blood collection tubes are designed to draw a predetermined volume of blood and other fluids. There are different types of tubes with different additives. To distinguish one tube from another, its color is indicated by the label. The tubes must be cleaned and sterile, and PPE is necessary at all times. To prevent contamination of the blood, workers should use an antiseptic handwash product with Chlorhexidine gluconate.
