MD 12C VARIO-B
This VARIO® pump provides precise vacuum control by adaptation of the diaphragm pump's motor speed. It provides an outstanding pumping speed even close to the excellent ultimate vacuum. The on-demand motor speed control results in unsurpassed total lifetime of service parts such as diaphragms. The three-stage chemistry-design MD 12C VARIO diaphragm pump offers an outstanding pumping speed and meets high vacuum requirements for most high boiling solvents.
Performance features
- automatic adaptation of the vacuum level throughout the process for high process reliability and unattended operation
- short process times due to zero-fluctuation (hysteresis-free) vacuum control, even for large amounts of vapor
- easily operated CVC 3000 vacuum controller with clear text menus, with integrated venting valve
- extraordinary diaphragm life, therefore minimum operational and servicing costs
- excellent chemical resistance
