Use of automatic devices for histological processing and staining of the tissues and certain characteristics of preparation of histological specimens

: The experience in using automatic devices AT-2, AT-3, AT-4 and in this connection some peculiar features of making histological preparations are discussed. Some modifications of treatment and paraffin embedding of pieces of the tissue are suggested. Recommendations concerning economizing reagents used in the automatic apparatus referred to above without lowering the quality of preparations are given. The technique described makes it possible to prepare specimens and to carry out investigations of bioptic materials in the course of 2-3 days (including the fixation period).
