Abstract
This centrifuge includes a chamber (5), a rotor (6) arranged therein, a device (8) for driving the rotation of the rotor, and a device (11) for cooling the atmosphere of the chamber. The device for cooling the atmosphere of the chamber includes a Ranque vortex tube (30), a cold outlet (33) which is connected to one inlet (66) of the chamber. The centrifuge includes a pressurized-gas supply circuit which is connected to an inlet (32) of the Ranque vortex tube and which is intended to be connected to a source (49) of pressurized gas. Application is to the centrifuging of biological products.
