A disc-type centrifuge is configured to use clean water as sealing water to be supplied at high pressure to a sealing mechanism unit. A pump is disposed on a circulation pathway connecting a sealing water tank, in which the sealing water is stored, and the sealing mechanism unit. The sealing water (clean water) is circulated between the sealing water tank and the sealing mechanism unit by the pump. The pump is connected to the drive shaft of a motor that supplies a driving force to a rotating shaft and bowl and is configured so that the pump is operated by receiving the driving force of the motor.

A method of evaluating a patient's hematocrit includes collecting a sample of blood in a capillary tube, and placing the capillary tube into a centrifuge having a rotor. The centrifuge has base with a center axis and a manual rotation member. The rotor spins in response to the manual rotation member being pulled by an operator, and the rotor is coupled for rotation to the base. The rotor including a plurality of microfluidic channels. The sample of blood is separated with the centrifuge into a red blood cell portion and a plasma portion in the microfluidic channels. A diagnosis image is provided including a base line indicia, a lower normal line indicia, an upper normal line indicia and a 100 % level line indicia. The capillary tube is placed against the diagnosis image with the bottom end placed adjacent the base line indicia.
