  Classification of centrifuge tubes

  1. Plastic centrifuge tube
     The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the sample can be taken out by the puncture method. The disadvantages are easy deformation, poor resistance to organic solvents, and short service life.

  Plastic centrifuge tubes are Disposable Medical Consumables, and it is not recommended to reuse them multiple times. In order to save costs, the PP centrifuge tube can be reused according to the situation, but it needs to be thoroughly sterilized by high temperature and high pressure to ensure the scientificity of the experimental results. The centrifuge tube made of PE cannot be sterilized by high temperature and high pressure.

  1. Glass centrifuge tube
     When using glass tubes, the centrifugal force should not be too large. Rubber pads are needed to prevent the tubes from breaking. High-speed centrifuges generally do not use glass tubes. The cap of the centrifuge tube is not well sealed, and the liquid cannot be filled up (for high-speed centrifuges and angle rotors are used) to prevent overflow and loss of balance. The consequence of spillage is to contaminate the rotor and centrifugal cavity and affect the normal operation of the sensor. During ultracentrifugation, the liquid must be filled with the centrifuge tube, because ultra-separation requires a high vacuum, and only by filling it can the centrifuge tube be prevented from being deformed.
  2. Steel centrifuge tube
     The steel centrifuge tube has high strength, no deformation, heat resistance, frost resistance, and chemical corrosion resistance. Its application is also quite extensive, but it should also be used to avoid contact with strong corrosive chemicals, such as strong acids and alkalis. Try to avoid the corrosion of these chemicals.

  Taizhou Huangyan Fangye Technology is a manufacturer and factory of Spin Columns and centrifuge tubes, specializing in the production and supply of spin columns and centrifuge tubes. There are mainly two types of round bottom and sharp bottom. Due to the special nature of the spin column material, it can withstand acid, alkali and Most organic solvents have no adsorption effect on most biomolecules. Our centrifuge tubes have excellent centrifugal stability to avoid sample loss during centrifugation. The cap is well sealed to prevent the sample from evaporating
