Low speed large capacity centrifuge classification of centrifuge tube
1, plastic centrifuge tube
Low speed large capacity centrifuge to understand plastic centrifuge tube strength is lit or semi transparent, its hardness is small, can remove the gradient puncture. The disadvantage is easy to deformation, anti corrosion of organic solvent is poor, with short life. Plastic centrifuge tube has a tube cover, its effect is to prevent the leakage of the samples, especially for the radioactive or strong corrosive sample to prevent leakage of the sample is very important; the tube cover another effect is to prevent sample evaporation and supporting centrifuge tube, preventing centrifugal tube deformation. Low speed large capacity centrifuge suggestions in the selection of the above point should pay attention to check whether the tube cover tightly, can cover tightly in the test, to arrive at the inverted no leakage; we all know that in a plastic centrifuge tube, the commonly used materials of polyethylene (PE), polycarbonate (PC), polypropylene (PP), the polypropylene PP pipe function will be relatively good, so, low speed and large capacity centrifuge suggest we in the selection of plastic centrifuge tube as possible when thinking of polypropylene plastic centrifuge tube.
2, glass centrifuge tube
Low speed large capacity centrifuge suggest using a glass tube centripetal force is too large, the demand of rubber mat pad, preventing the pipe broken, high-speed centrifuges generally do not use glass tube. The lid closed good enough centrifugal tube, liquid will not fill (for high-speed centrifuges and use angle rotor) to prevent spillover, lose balance. Spillover results is pollution rotor and the centrifugal cavity, affect the normal work of the sensor. Ultracentrifugation, liquid must fill in centrifuge tube, because from the ultra high vacuum pumping and demand, just fill in order to prevent the deformation of the centrifugal tube.
3, steel centrifugal tube
The steel pipe centrifugal strength, no deformation, can resist heat, frost resistance, resistance to chemical corrosion, low speed and large capacity centrifuge to know its application is also appropriate to use the same throughout but also should prevent chemicals touch strong corrosive, strong acid or alkali. To prevent corrosion of these chemicals.
Effect on centrifugal tube cover low speed large capacity centrifuge:
Plastic centrifuge tube with a tube cover, a tube cover needs cover tightly, to prevent the liquid leakage out of.
1, used for radioactive or strong corrosive sample, to prevent the leakage of the sample.
2, to prevent sample evaporation.
3, support the centrifuge tube, preventing centrifugal tube deformation.
