Plastic vacuum desiccator with a one-piece injection-molded polycarbonate (PC) body, dual valves and a built-in negative-pressure gauge. Used to dry and store moisture-sensitive samples such as biochemical reagents, pharmaceuticals, optical lenses, precision components, seeds and archival items. Available as a standalone desiccator in clear or amber PC, as a desiccator + oil-free vacuum pump kit, or as a standalone oil-free vacuum pump.
Features
Thick-walled polycarbonate body, injection-molded in one piece for pressure and impact resistance; high transparency lets you check samples at any time
O-ring seal: vacuum level changes by less than 6% after 31 days under vacuum
Dual-valve design: top and side needle valves can be connected at the same time, e.g. to backfill inert gas or keep samples under vacuum in an inert atmosphere
Negative-pressure vacuum gauge shows chamber pressure in real time
Perforated shelf plate included; amber version shields light-sensitive samples
Oil-free vacuum pumps: maintenance-free, adjustable flow, usable for both vacuum and positive pressure
