Microscopic object high pressure observation unit for biotechnology has O ring low pressure and progressive metal high pressure seals with conical optical viewing disc, evacuation and pressurization channels

摘要

A microscopic object high pressure observation unit is sealed by an O ring (6) at low pressure and by the forcing together of two surfaces in a progressive metal seal (7) at high pressure and has conical optical discs (8) with low optical refraction coefficient for microscope viewing of a sample chamber with rapid evacuation channel (4) in the cover (2) an high pressure feed (3) in the base (1).
