　There are many types of consumables in laboratories, and the most frequently used consumables may be those pipe consumables, such as centrifuge tubes. Centrifuge tubes, as the name suggests, are mainly used in conjunction with centrifuges and are unavoidable consumables.
　First of all, the classification of centrifuge tubes can be broadly distinguished according to their material properties. In this way, centrifuge tubes can be divided into glass centrifuge tubes and plastic centrifuge tubes. Among them, the plastic centrifuge tube can be subdivided into PP, PC, PS, etc. According to different needs, the manufacturer will choose different plastic materials for production.

　 Centrifuge tubes are classified by material:
　　 can be divided into plastic centrifuge tubes, glass centrifuge tubes and stainless steel centrifuge tubes.
　　There are plastic and glass centrifuge tubes commonly used in laboratories. Generally, plastic tubes are used more, because glass centrifuge tubes cannot be used in high-speed or ultra-speed centrifuges. Plastic centrifuge tubes are made of PP, PC, PE and other materials. The performance of PP pipe is relatively good. The plastic centrifuge tube is transparent or translucent, and you can visually see the centrifugation of the sample, but it is relatively easy to deform and has poor resistance to organic solvents, so it has a short service life. Therefore, such centrifuge tubes are usually purchased frequently in laboratories.
　　PP: translucent, with good chemical and temperature stability, but it will become brittle at low temperatures, so don't centrifuge it below 4°C.
　　PC: good transparency, high hardness, high temperature sterilization, but not resistant to strong acids and alkalis and some organic solvents such as alcohol. Mainly used for ultra-high speed centrifugation above 50,000 rpm.
　　PE: Opaque. It does not react with acetone, acetic acid, hydrochloric acid, etc., is relatively stable, and tends to become soft at high temperatures.
　　PA: This material is a polymer made of PP and PE. It is translucent and has very stable chemical properties, but it is not resistant to high temperatures.
　　PS: Transparent, high hardness, stable to most aqueous solutions, but will be corroded by a variety of organic substances, it is mostly used for low-speed centrifugation, and is generally for one-time use.
　　PF: translucent, can be used at low temperature, if it is an experimental environment at -100℃-140℃, centrifuge tubes of this material can be used.
　　CAB: transparent, can be used for the gradient determination of dilute acids, alkalis, salts, alcohol and sucrose.
