血清学实验室在测定血型和交叉配血时都需要用离心机分离血浆或血清,洗涤红细胞,加速凝结过程等等。然而实验室人员在处理血液标本时,很易遭到血清肝炎等的传染,特别是在使用按传统设计的离心机时。通常台式或立式离心机都采用冷循环气流来减少摩擦造成的温升。冷气流流过离心腔, Serological laboratories in the determination of blood type and cross-matching blood need to use centrifuges to separate plasma or serum, washing red blood cells, accelerate the coagulation process and so on. However, laboratory personnel are susceptible to the spread of serum hepatitis when handling blood samples, especially when using conventionally designed centrifuges. Typically, both benchtop or vertical centrifuges use a cold circulation gas flow to reduce the temperature rise caused by friction. Cold air flow through the centrifugal chamber,
