Centrifuge tube is a disposable laboratory consumable made of polymer polypropylene (PP) material, Usually used in conjunction with a centrifuge for the separation and preparation of various biological samples.

The centrifuge tubes are mainly divided into large capacity centrifuge tubes (250mL, 500mL), conventional centrifuge tubes (15mL, 25mL, 50mL), and micro centrifuge tubes (0.7mL, 1.5mL, 2.0mL). The large capacity centrifuge tube is the centrifugal choice for lar- ge capacity cell collection, pelleting and protein purification; the conventional centrifuge tube is mainly used for centrifugal collection of cells and biological macro molecules, photosensitive samples and storage of special chemiluminescent reagents; the micro cen- trifuge tube needs to be used in conjunction with micro centrifuges for micro reagents separation, Sample preparation and storage.
