title: [Devices facilitating the preparation of biological specimens for electron microscopy].
abstract: The construction of a matrix is described which facilitates the process of placing biological objects into polymer media in order to prepare ultrathin sections without the employment of gelatin, starch and polyethylene capsules that can be used only once. The construction of a reactor for cytochemical assays is presented. The apparatus can be used to locate enzymes within the cell, and to identify microorganisms. A modification of the dialysis technique for microbiological objects is proposed which accelerates and simplifies the process.
