Description

DESCRIPTION

These powerful rotary vane pumps feature an unusually compact design and low weight for pumps of this capacity. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium to increased gas flow rate. Rotary vane pumps are used where an ultimate vacuum between a few mbar and down to 10^-3 mbar has to be attained. Typical applications are degassing, lyophilization, fine vacuum distillation, and drying chambers.
