Function And Method of Centrifuge Tube
Anticoagulant plasma collection: Collect anticoagulant whole blood, gently reverse the full anticoagulant, can directly centrifuge the plasma at low speed (can also stand for about half an hour and then centrifuge the plasma at low speed) for use or storage. According to the performance characteristics of different anticoagulants, the appropriate anticoagulants were selected. Laboratory commonly used anticoagulant heparin salts, EDTA and citrulate sodium.
The selection of anticoagulant points of attention: (1) the amount of anticoagulant added to each sample should be consistent, and the amount of whole blood taken should also be consistent as far as possible; ② After collecting anticoagulant whole blood, it must be gently reversed to fully anticoagulant to prevent part of the blood from not contacting anticoagulant and causing coagulation. ③ The plasma collected in anticoagulant whole blood is relatively large (1ml anti. Folding inspection instrument to check whether the pipette nozzle and nozzle damage, if damaged, can not be used; After washing the instrument with tap water, soak it in chromic acid washing solution. The operation method is as follows: hold the pipette or pipette in the right hand, with the index finger close to the upper mouth of the tube, and the middle and ring fingers open.
