ENVIRONMENTAL EQUIPMENT FOR BIOLOGY EXPERIMENT

摘要

PROBLEM TO BE SOLVED: To provide an environmental equipment for biology experiments which enables the cleanliness of clean space to reliably be maintained and safely be realized at a low cost. SOLUTION: A transparent titanium oxide membrane is formed on the surface of a metallic plate 6 and a shutter 5 made of transparent glass which are partition walls surrounding/forming clean working space S of a clean bench 1. When the clean bench 1 is unused, the titanium oxide membrane is activated under exposure to ultraviolet rays from a germicidal lamp 11 and miscellaneous germs, etc., adhered to the titanium oxide membrane are reliably sterilized by photocatalytic reaction. Since all surfaces of partition walls for the clean working space S are covered with the titanium oxide membrane and are photocatalytically activated e.g. with a germicidal lamp 11, a clean working space S having a high sterilizing characteristics can be realized.
