There Are Also Many Kinds Of Plastic Centrifuge Tubes

For the classification of centrifuge tubes, they can be distinguished according to their material properties, so that centrifuge tubes can be divided into two categories: glass centrifuge tubes and plastic centrifuge tubes. Among them, the centrifuge tubes made of plastic can be subdivided into PP, PC, PS, etc. According to different needs, manufacturers will choose differently
Made of the same plastic material.

There are plastic and glass centrifuge tubes commonly used in laboratory centrifuges. Generally, plastic centrifuge tubes are used more, because glass centrifuge tubes cannot be used in high-speed or ultracentrifuges. Plastic centrifuge tubes are also made of PP (polypropylene), PC (polycarbonate), PE (polyethylene), and other materials. The performance of PP pipes is relatively good. The plastic centrifuge tube is transparent or translucent, which can visually see the centrifugation of the sample, but it is relatively easy to deform and has poor corrosion resistance to organic solvents, so the service life is short.

1. PP (Polypropylene): Translucent, good chemical, and temperature stability, but it will become brittle at low temperature, so do not be below 4°C during centrifugation.

2. PC (polycarbonate): good transparency, high hardness, can be sterilized at high temperature, but not resistant to strong acid and alkali and some organic solvents such as alcohol. To be used for ultracentrifugation above 50,000 rpm.

3. PE (polyethylene): opaque. It does not react with acetone, acetic acid, hydrochloric acid, etc., and is relatively stable, and it is easy to become soft at high temperatures.

4. PA (polyamide): This material is a polymer of PP and PE material, translucent, very stable in chemical properties, and not resistant to high temperatures.

5.PS (polystyrene): transparent, high hardness, stable to most aqueous solutions, but will be corroded by a variety of organic substances, mostly used for low-speed centrifugation, and generally one-time use.

6. PF (polyfluorene): translucent, can be used at low temperature, if it is an experimental environment at -100-140°C, centrifuge tubes of this material can be used.

7.CAB (cellulose acetate butyl): transparent, can be used for the gradient determination of dilute acids, alkalis, salts, as well as alcohol and sucrose.
