It can be divided into plastic centrifuge tubes, glass centrifuge tubes, and stainless steel centrifuge tubes.

Commonly used centrifuge tubes in laboratories include plastic and glass. Generally, plastic is used more, because glass centrifuge tubes cannot be used in high-speed or ultracentrifuges. Plastic centrifuge tubes are made of PP, PC, PE, and other materials. PP pipe performance is relatively better. The plastic centrifuge tube is transparent or translucent, and the centrifugation of the sample can be seen intuitively, but it is relatively easy to deform and has poor corrosion resistance to organic solvents, so the service life is short. Therefore, such centrifuge tube laboratories generally buy frequently.

PP: Translucent, with good chemical and temperature stability, but it will become brittle at low temperatures, so do not centrifuge below 4°C.

PC: It has good transparency, and high hardness, and can be sterilized by high temperature, but it is not resistant to strong acids and alkalis and some organic solvents such as alcohol. It is mainly used for ultra-high-speed centrifugation above 50,000 rpm.

PE: Opaque. It does not react with acetone, acetic acid, hydrochloric acid, etc. It is relatively stable and tends to soften 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: It is transparent, hard, and stable to most aqueous solutions, but it will be corroded by various organic substances, and it is mostly used for low-speed centrifugation, and it is generally for one-time use.

PF: Translucent and can be used at low temperatures. If the experimental environment is -100°C-140°C, you can use a centrifuge tube made of this material.

CAB: transparent, can be used for the gradient determination of dilute acid, alkali, salt, alcohol, and sucrose.
