ABSTRACT:
The present invention relates generally to laboratory apparatus and more particularly to disposable suspended magnetic stirrers. An apparatus having a stirring vessel closure and a stirring vessel is disclosed. The stirring vessel closure includes a suspended magnetic impeller, the elevation of which is adjustable by a moveable bearing. The invention is particularly suitable for applications in which solids must be suspended in a liquid medium with a minimum of shear forces, such as in the suspension of tissue cell cultures in a growing medium. The disclosed stirring vessel closure has inclined access ports to allow improved pipette accessibility to the interior of the stirring vessel while also providing improved close packing of stirring vessels during usage or storage.
