摘要: A method for separating serum from whole blood in a vessel at an insertion speed of 30 cm/sec or less and maintaining the suction pressure of the suction nozzle at 400 mm Hg or less. Improved analytical results are obtained because the serum can be produced without hemolysis.

摘要: The blood filter unit of the invention is composed of a blood filtering material made of glass fiber filter and microporous membrane and a holder having a blood inlet and a filtrate outlet. The holder accommodates the blood filtering material so that the microporous membrane is located on the filtrate outlet side, provides a space between the blood filtering material and the filtrate outlet, and provides a means for preventing adhesion of the blood filtering material on the filtrate outlet side. By using the blood filter unit, a necessary volume of plasma or serum for analysis can be separated surely, irrespective of hematocrit value of the blood.

摘要: A blood filter unit having a blood filter holder containing a blood filtering material of a glass fiber filter and a microporous membrane is described. The holder has a blood inlet and a filtrate outlet, and accommodates the blood filtering material so that the microporous membrane is located on the filtrate outlet side and has a space between the blood filtering material and the filtrate outlet. The holder provides means for preventing adhesion of the blood filtering material on the filtrate outlet side. The inventive blood filter unit allows separation of a desired volume of plasma or serum for analysis without interference by the hematocrit value of the blood.
