Centrifuge Tube/Cryovial Tube

Cryovials are polypropylene tubes that can be autoclaved. Polyethylene, including polypropylene, is classified as a polyolefin, which is a compact-molecular hydrocarbon. It has the same chemical composition as polyethylene, but each unit has a methyl group added to it. Its chemical composition allows it to be non-toxic, non-contaminating, and lighter than water. Polyethylene is the best material for manufacturing cryovials because of the characteristics listed above. Cryovials are meant to retain biological material at low temperatures of around -196 degrees Celsius. At such low temperatures, most materials will degrade, which is why polythene is the best material to use. 

Centrifuge tubes are distinguished from normal tubes by their use in centrifugation. Centrifugation is the process of spinning liquids at high speeds to separate their constituents. The following are the main applications for centrifuge tubes:

• Sample processing 

   A contamination can sometimes make its way into a sample that needs to be analyzed. The purpose of sample processing is to eliminate the contaminant so that the sample can be investigated properly. This is where centrifugation comes into play. 

• Medical laboratories

Centrifuge tubes are essential in medical labs for separating components. They can separate organelles from cells and sediment cells and viruses in blood samples. Centrifugation is a critical step in extracting DNA or RNA from a cell.

• Maintaning your instrumentation

Laboratory instrumentation is expensive and analysts must do their diligence when protecting them from harmful samples. Centrifuge tubes are a key to keeping your equipment healthy and thus your productivity high.
