Theory of Operation
The Hematek Slide Stainer is designed to produce stained slides of consistent quality in a
continuous process. This is accomplished by having a fixed length of time in each of the
three phases of stain, buffer, and rinse, as well as a predetermined ratio of stain-to-buffer
volumes in the buffer phase.
A properly stained slide is the result of an interactive process involving the pump
volumes, the mixing process, and the stain-to-buffer ratio. A minimum ratio of 1:2 is
recommended; however, if the platen is filling properly, good mixing is occurring, and the
stained slides are acceptable under the microscope, the stain-to-buffer ratio should not be
adjusted.
