Chemistry diaphragm pump MD 4C NT VARIO Vacuubrand

VARIO® pumps provide precise vacuum control by adaptation of the diaphragm pump´s motor speed. The three-stage chemistry MD 4C NT VARIO diaphragm pump meets high vacuum requirements for most high boiling solvents. The on-demand motor speed control results in unsurpassed lifetimes of service parts, such as diaphragms.
