Equipment for Simultaneous Processing of Groups of Slides for Radioautography

Abstract

The equipment consists of commercially available 5-slide plastic grips (obtained from Lipshaw Manufacturing Co., 7446 Central Ave., Detroit, Mich. 48210) and specially designed lightproof exposure boxes to hold the grips. After deparaffinization and hydration, slides are inserted into the grips, dipped in liquid emulsion, drained, and sealed in the exposure box. After exposure, the 5-slide units are removed from the box (in darkness) and inserted into specially made Plexiglas racks that hold four 5-slide units (20 slides). Photographic developing, fixing, and washing are performed by immersing the 20-slide group in fluids contained in 30-slide glass staining dishes (Lipshaw No. 122 dishes). The equipment simplifies darkroom operations and provides means for standardizing the preparation of radioautographs.
