Abstract

A preparation-making ultracentrifuge is disclosed comprising a magnetic suspension and an electric motor, which are disposed within its casing, said magnetic suspension consisting of a permanent magnet with a magnetic circuit, the armature of said electric motor being made in the form of a sleeve fixedly secured to the centrifuge rotor is disclosed. Such construction of a preparation-making ultracentrifuge enables the rotor to be accelerated to the required speed within a comparatively short time period and allows a reduction in the weight of the electric motor armature.

Claims8
