A centrifuge including a rotor, a rotor chamber accommodating therein the rotor and having an opening, a motor configured to rotate the rotor, a door configured to close the opening of the rotor chamber, an input unit configured to receive an input of an operation condition, a display unit configured to display an operating status, and a control unit configured to control rotation of the motor, wherein the control unit is configured to perform a program operation under an operation condition including a plurality of steps, and wherein the control unit is configured so that a specific step of stopping the rotation of the rotor and permitting the door to be opened or closed can be set as at least one of the plurality of steps.

Centrifuge having a stopping step between centrifuging steps

A centrifugal separator includes an input section for allowing a user to enter operating conditions of a centrifugal separation of a sample accommodated in a rotor driven by a motor. A memory of the centrifugal separator stores a user ID code and a corresponding user name which are registered in advance by the user. Operation of the centrifugal separator is allowed when a user ID code entered through the input section agrees with the registered user ID code.

In determining the effectiveness of parameters on cells, after treatment of the cells with one or more selected parameters, the results of the treatment can be quickly determined by measuring the number n.sub.0 of cells having a predetermined cell form, subsequently mechanically stressing the cells for a sufficient period of time t to change the cell form substantially, thereafter again measuring the number n of cells having the predetermined cell form, and determining the cell viability .tau.defined by .tau.=t/1n(n.sub.0 /n).
