Type EFPA-30 apparatus for electrophoresis on cellulose acetate films was developed at the Specialized Design Office for Biophysical Equipment of the Moscow Research and Production Association BIOFIZPRIBOR. Three autonomic separation cameras are united in one block, that permits separation of 12, 24, and 36 samples; the apparatus is supplied with time transducer, acoustic and visual indication. Clinical trials of the apparatus were carried out at the Institute of Biological and Medical Chemistry of the USSR Academy of Medical Sciences, its commercial production is to be started. The apparatus is intended for protein separation and may be used for studies of hemoglobins, serum proteins, lipoproteins, enzymes, and other biologic compounds. Methods for hemoglobin and serum protein separation are presented.
