Das Autoselect‐System – ein Automatensystem zur Selektion von Antibiotikaproduzenten. VI. Achtfach‐Stanzautomat

Abstract

An eightfold punch belonging to the Aùtoselect‐system is described. It is provided for the preparation of bioassay plates. From the agar of large quadratic test plates moving automatically on a carriage of the machine, 64 holes are made by eight punches. The punches arranged in a row over the test plate are lowered, if the carriage stops, and so they cut out and exhaust agar discs in a pattern of 8 × 8.
