Cassettes
Tissue Cassettes
Allows infiltration, embedding, sectioning and filling steps to be done with a single specimen container.
They have a plastic lid & base which are resistant to solvents, microwaving techniques and
decalcifying solution. Their universal size fits all popular base molds and they may be used with stainless
steel process covers. The unique patented design permits maximum fluid exchange and drainage.
