A Tissue Basket for Paraffin Infiltration

Abstract

The processes of washing, dehydration and paraffin infiltration when large numbers of tissues must be individually identified are always laborious. Washing and dehydration can be carried out in individual glass vials with relative ease and fairly rapidly if gravity flow reagent bottles are used to fill the vials. The use of similar vials for paraffin infiltration is usually complicated by hardening of the paraffin if too many vials are removed from the oven at once, or by cooling of the oven itself if it is too frequently opened. The same criticism applies to the process of embedding tissues when large numbers of vials must be handled simultaneously.
