Centrifuge tube material introduction-GST centrifuge tube automatic production line

　　GST centrifugal tube automatic production line is used for automatic feeding, automatic printing, automatic drying, automatic capping, automatic detection, automatic bagging, automatic packaging and automatic coding of centrifugal tubes.GST centrifugal tube automatic production line has the characteristics of accurate feeding; good screen printing; adjustable capping; neat bagging and adjustable packaging quantity. Here is a look at the material introduction of centrifugal tubes following GST Technology!

　　Glass centrifuge tubes: cannot be used in high and ultra high speed centrifuges, only for low speed centrifuges.

　　PP (polypropylene): translucent, good chemical and temperature stability, but will become brittle at low temperatures, so do not centrifuge below 4°C.

　　PC (polycarbonate): better transparency, hardness, can be sterilised at high temperatures, but not resistant to strong acids and bases and some organic solvents such as alcohol. It is mainly used for ultra-high speed centrifugation above 50,000 rpm.

　　PE (polyethylene): opaque. It does not react with acetone, acetic acid, hydrochloric acid, etc. It is more stable and easily becomes soft at high temperatures.

　　PA (polyamide): this material is a polymer of PP and PE material, translucent, chemically very stable, single not resistant to high temperatures.

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

　　PF (polyfluoro): translucent, can be used at low temperatures, if it is an experimental environment at -100°C - 140°C, you can use centrifuge tubes made of this material.

　　CAB (cellulose butyl acetate): transparent, can be used for more dilute acids, bases and salts, as well as for gradient determination of alcohols and sucrose.

　　CN tubes: softer and transparent, but not resistant to strong acids and bases and certain organic solvents, and cannot be autoclaved. Suitable for density gradient centrifugation of sucrose, glycerol, etc. Should be transparent and easy to collect.

　　Steel centrifuge tubes: strong, not deformed, resistant to heat, frost and chemical corrosion, widely used, but avoid contact with strong corrosive chemicals when used.

　　Cautions.

       1. The use of organic solvents in plastic tubes must comply with the compatibility regulations with the corresponding materials. Polypropylene (PP) centrifuge tubes (bottles) cannot be used in contact with petrol, paraffin, etc. Polycarbonate (PC) centrifuge tube (bottle) can not be used in contact with gasoline, acetaldehyde, acetone, ethanol, isobutanol, cresol, etc. Polyethylene (PE) centrifuge tubes (bottles) should not be used in contact with sulphuric acid (50%, 75%), benzene, petrol, paraffin, etc.

　　2. Centrifuge tubes should be disinfected under high temperature and pressure, and the caps should be separated from the tubes.
