It is a tube rack consisting of two waffer cassettes and usually made from metal. The microtubes can be placed between the two cassettes to keep the tube lips tightly closed during incubation in the boiling water.
When using a test tube rack, ensure it is placed on a stable, flat surface to prevent tipping. Always check that the test tubes are securely seated in the rack to avoid spills or breakage. Handle test tubes with care, especially if they contain hazardous substances, and wear appropriate personal protective equipment, such as gloves and safety goggles. Finally, keep the rack clear of clutter to minimize the risk of accidents.
