microtube

A microtube is a small, often disposable, plastic tube used in laboratories for handling and storing small volumes of liquids or samples. Typically, these tubes are made of polypropylene, a material chosen for its chemical resistance and ability to withstand temperature changes. Microtubes come in various sizes, with capacities ranging from a few microliters to several milliliters, with common sizes being 0.5 mL, 1.5 mL, and 2.0 mL.

These tubes are characterized by their cylindrical shape, a conical or rounded bottom, and a hinged or separate lid to prevent evaporation and contamination. The lids are designed to seal securely, often with a snap-fit mechanism. Many microtubes also feature frosted surfaces on the side or cap, which can be used for labeling with pens or markers.

Microtubes are indispensable tools in molecular biology, biochemistry, clinical diagnostics, and many other life science research fields. They are used for a wide array of applications, including sample preparation, centrifugation, incubation, storage of reagents and biological samples like DNA, RNA, and proteins, and for performing reactions such as PCR (polymerase chain reaction). Their small volume capacity reduces waste of precious reagents and samples, and their disposable nature helps prevent cross-contamination. The compatibility of microtubes with standard laboratory equipment, such as centrifuges and heating blocks, further enhances their utility.
