Abstract
An apparatus and method for staining cell objects on microscope slides includes a container for holding a staining solution and for holding one or more of the slides having the cell objects thereon. The container is preferably a Coplin jar in which is disposed a perforated cage containing a magnetic stirrer. Lower ends of the slides rest on the top of the cage and the stirrer drives liquid in and out of the cage and stirs and mixes the stain solution to obtain uniformity of stain concentration throughout the Coplin jar. A magnetic drive unit is positioned below the container and magnetic flux travels through the imperforated bottom wall of the glass Coplin jar to couple the stirrer rod to rotate within the cage, as the magnetic driver rotates in the unit beneath the jar.
