Basic Classification Of Centrifugal Tubes

Basic classification of Centrifugal tubes:

1. Plastic Centrifugal Tube

The advantages of the plastic centrifugal tube are transparent or translucent, and its hardness is small and the gradient can be removed by puncture. The disadvantage is easy to deform, resist the corrosion of the organic solvent is poor, the service life is short.

2. Glass Centrifugal Tube

The use of glass tube centrifugal force should not be too large, need to cushion rubber pads, to prevent the tube broken, high-speed centrifuges generally do not choose glass tube.

3. Steel Centrifugal Tube

Steel centrifugal tube strength, deformation, heat resistance, antifreeze, chemical corrosion resistance, its application is also quite extensive, but also should avoid contact with strong corrosive chemicals, such as acid, alkali and so on. Try to avoid the corrosion of these chemicals.

Plastic centrifugal tubes are generally used. The plastic centrifuge tubes used in the laboratory have a tube lid, and its role is to prevent the leakage of samples, especially for radioactive or strongly corrosive samples to prevent the leakage of samples, there is a tube cover can be very good to ensure this. Thugnes also has a role in preventing the evaporation of samples and supporting the centrifugal tube to prevent deformation of the centrifugal tube. In selecting this point also should pay attention to check whether the tube cover is tight, in the test can be covered to reach the inverted liquid. If the selection does not pay attention to the inspection of the tube cover, in the case of leakage, it is likely to lead to experimental errors, serious words can also lead to the occurrence of accidents. It is important to check the tightness at the time of selection.

The concept of centrifugal tube technology:

The platelet concentrate derived from the autogenous venous blood after centrifugation by gradient density was added to the gel to form a gelatinous substance, which was used together with autogenous bone, allogeneic bone, allogeneic bone, stem cell and other biomaterials to induce tissue regeneration in the tissue Defect Department. The centrifugal tube can release many growth factors to promote the cascade reaction of tissue healing, and achieves the regeneration and repair of autologous tissue. This is the Autologous cell regeneration technique [autologous cellerlar rejuvenation–acr]2 Centrifuge Tube preparation process: Taking whole blood, using different blood components (serum PPP, centrifugal tube, red blood cell) sedimentation rate difference, The first centrifugal: after the gradient centrifugation the blood into three layers: serum, (for the plasma of the spent platelets), the second layer of platelet-rich plasma is the centrifuge tube, the third layer contains a large number of red blood cells (red blood cells).

Second centrifugal: The first centrifugal tube part of the extraction, the remaining serum and red blood cells by changing the rotational speed and centrifugal force in the size of the 2nd centrifugal, again to obtain the remaining part of the centrifuge tube, so that through two times centrifugal enrichment can obtain high concentration of platelet-rich centrifuge tube. The platelet concentration in the centrifuge tube can reach 16 times times the total blood. When used in the centrifugal tube to add a lectin, so that it becomes gel-like, at this time the growth factor in the centrifuge tube is fixed in the clot, not easily lost and conducive to play its role.
