Laboratory Vacuum Drying Oven

Laboratory Vacuum Drying Oven

Instrumentused for drying of heat- sensitive, easily decomposed and easily oxidized substances.
Vacuum ovens show with short heating up times,
High precision temperature control and turbo drying.
Heating and oxygen sensible materials are treated with incomparable care.
Digital pressure control and with controllable pump for installation in a lower chamber, the pump module, installed on the outside of the vacuum oven.
