Abstract

1,189,195. Centrifuges. MSE. HOLDINGS Ltd. 27 July, 1967 [17 June, 1967], No. 28277/ 67. Heading B2P. In a zonal centrifuge having a casing 1 within which a cylindrical rotor 8 is driven at its lower end by an electric motor, the rotor extends through an aperture 9 in a cover 2 of the casing and is rotatably supported at its upper end in a bearing within a housing 10 which carries an arrangement 11 for liquid supply and exit to and from the rotor respectively. The housing 10 comprises an annular portion 12 which fits within the aperture 9, an O-ring 13 providing a vacuumtight seal between the cover 2 and the portion 12. The cover 2 is sealingly slidable on the casing 1 which is under vacuum. The rotor is surrounded by a bowl 6 secured to the housing of the driving motor and surrounded by cooling coils. Coolant is fed at 20 and 21 to a top bearing 22 and a rotating seal 23 respectively. In operation, coolant is fed to bearing 22 and seal 23 and the rotor is first run at slow speed so that an O-ring valve 26 seals off the passage 25. A gradient solution is pumped into the rotor, light end first, through tube 18 and passages 24 until the rotor is full as indicated when the light end of the solution flows through passages 30, 28 and emerges from tube 19. The rotor is then run at high speed, when the valve 26 opens. A particulate sample, e.g. virus, in a carrier liquid of density lighter than the inner, lightest zone of the gradient solution in the rotor, is introduced continuously through the tube 19. The carrier liquid enters the annular rotor space 17 at its lower end, travels along the outer surface of the rotor core 29, enters the passages 27 and eventually emerges from the tube 18. The sample particles leave the carrier liquid during its passage through the rotor and become distributed into zones of the gradient solution according to their densities. The rotor may then be unloaded by reducing its speed to close valve 26 and by pumping a fluid of density greater than the densest part of the gradient solution through tube 18. This displaces the gradient solution, lightest end first, through the tubing taking with it the separated bands of the sample particles. The description refers to a known centrifuge made of TITANIUM.
