Centrifuge tubes are classified by capacity:
　　Microcentrifuge tube, usually, the capacity of the centrifuge tube is divided into 1.5ml, 2ml, 5ml, 10ml, 15ml, 50ml, etc. According to the online survey, as a domestic centrifuge tube, it usually mainly has the above specifications. The more commonly used ones are 10ml and 50ml.
　　Ordinary centrifuge tubes (50mL, 15mL), common centrifuge tubes in Zui laboratory;
　　Microcentrifuge tubes (2mL, 1.5mL, 0.65mL, 0.2mL) are often used in conjunction with a microcentrifuge for the separation of trace reagents and are often used in molecular biology micromanipulation experiments.
　　Other specifications include 30ml, 7ml, etc., which are mainly adapted to different centrifuges.

　　 Classified by bottom shape:
　　According to the shape, the centrifuge tube can also be divided into round bottom and pointed bottom, as well as screw cap and plug cap. The screw cap centrifuge tube has a fine scale, and the plug cap has only an overall capacity indicator.
　　Round-bottom centrifuge tube: When performing density gradient collection, you can choose a round bottom; the round bottom has a large area and can withstand greater centrifugal force than a sharp bottom;
　　 Sharp-bottomed centrifuge tube: When the sample is small, when collecting the sediment, it is better to separate with the sharp-bottomed one, and the upper layer is easier to suck with a pipette.
　　Flat-bottomed centrifuge tube: The purpose is the same as that of sharp-bottomed centrifuge tube, but the centrifuge tube can be erected, which is more convenient to put in the experiment.

　　 Classified by lid:
Centrifuge tube caps are generally small-capacity centrifuge tubes with caps, while ordinary-capacity centrifuge tubes have caps, plug-in caps and screw caps. Centrifuge tubes with a capacity of 50ml or more are basically screw caps. host.
　　 Generally speaking, centrifuge tubes with caps are marked with graduations on the wall, while centrifuge tubes with screw caps have finer graduations, while the cap has only an overall capacity mark.
