Abstract
A laboratory centrifuge is known with a centrifuge housing which contains a motor and a rotor connected with the motor through a drive shaft, the motor being held in the motor housing which includes an upper end shield and a lower end shield, and with the motor having a rotor tank arranged above it which has a passage for the drive shaft on the motor side. In order to indicate, starting from here, a laboratory centrifuge which is economical to manufacture and simple to assemble, which can be cooled easily, if necessary, it is proposed that the rotor tank and the upper end shield be made as a single piece.
Claims15
A laboratory centrifuge comprising:
- (a) an upper housing portion having a rotor chamber formed therein;
- (b) a lower housing portion attached to the upper housing portion, the upper housing portion and lower housing portion bounding a motor chamber therebetween;
- (c) a drive shaft extending between rotor chamber and the motor chamber;
- (d) a centrifuge rotor being disposed within the rotor chamber and coupled with the drive shaft;
- and
- (e) a motor rotor and motor stator being positioned within the motor chamber, the motor rotor being coupled with the drive shaft, the motor stator being in abutting contact with the upper and lower housing portions, the motor rotor and motor stator being within the motor chamber such that the upper housing portion and lower housing portion function as the sole housing for the motor rotor and motor stator.
A laboratory centrifuge comprising:
- (a) an upper housing portion having a rotor chamber formed therein;
- (b) a lower housing portion removably attached to the upper housing portion;
- (c) a drive shaft having a lower end rotatably attached to the lower housing portion and an upper end extending through the upper housing into the rotor chamber;
- (d) a centrifuge rotor being disposed within the rotor chamber and coupled with the upper end of the drive shaft;
- (e) a motor stator being disposed between and in abutting contact with the upper housing portion and the lower housing portion such that the upper housing portion and lower housing portion function as the sole housing for the motor stator;
- and
- (f) a motor rotor mounted to the drive shaft and disposed within the motor stator.
