Several types of rubber stoppers are used in blood collection tubes. These types of stoppers are generally made of different synthetic rubbers. These stoppers are color coded according to the additives that are used in the tubes.
Blood collection tubes are available in a number of different sizes. These tubes are sealed to prevent contamination of the contents. They also have a different coating to prevent breakage when centrifuging or storing the tubes.
A rubber stopper prevents the entry of airborne contaminants and other chemicals into the tube. It also has a self-sealing feature that helps it to maintain a vacuum. These stoppers are used in many disposable blood collection tubes. They are also widely used as mechanical stoppers. They are available in different colors, such as green, pink, lavender, and tan.
In addition to being used in blood collection tubes, rubber stoppers are also used in test tubes. These stoppers are available in one-hole and two-hole varieties. One-hole rubber stoppers are generally used in laboratories. Two-hole rubber stoppers are made from soft material that prevents chemical leaks.
A rubber stopper can be used to prevent blood from leaking onto the needle or the venipuncture site. A high-quality rubber stopper provides a tight seal and lower pulling forces. Moreover, they also have lower impurities and residuals.
