Abstract
A centrifuge includes a rotor, a rotation shaft which has a through-hole communicated with an interior of the rotor, a face seal which slidingly contacts an end of the rotation shaft and has a path communicated with the through-hole of the rotation shaft, a wall member which accommodates the face seal, a sample transfer unit which transfers a sample through the rotor, and a coolant circulation unit which circulates a coolant to the wall member. The sample transfer unit transfers the sample by pressure so that a pressure of the sample flowing through a portion where the rotation shaft and the face seal slidingly contact with each other is higher than a pressure of the coolant flowing through the wall member.
