Four-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet highest requirements. The four-stage design of the eight-cylinder pump MV 10C NT provides the advantageous combination of high pumping speed and very low ultimate vacuum of 0.9 mbar in a very compact design. All internal parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. Upgraded with an exhaust waste vapor condenser (EK) the MV 10C NT +EK provides an excellent, environmentally friendly system with efficient solvent recovery. A separator for the inlet (AK) made of glass (with protective coating) against particles and liquid droplets is available as an optional accessory.

Performance features
• outstanding chemical resistance and superior vapor tolerance
• reduced process time due to very high flow rates even close to ultimate vacuum
• very low vibration and quiet
• excellent ultimate vacuum even with gas ballast
• on models with EK: excellent environmental friendliness due to efficient solvent recovery

Four-stage diaphragm pumps like the MV 10 NT VARIO select are excellent solutions for continuous, oil-free pumping of non-corrosive gases to vacuum levels that are only a fraction of a millibar. With its high pumping speed, this pump is an excellent option for higher gas load applications or rapid pump down of vacuum chambers.

All wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The MV 10 NT VARIO select automatically adapts its motor speed to hold the desired vacuum level. That also means the pump is whisper-quiet and generates ultra-low vibrations, and has high leak tightness. The highly flexible fabric-reinforced double FKM diaphragm is ideal for extended operating life.

The VARIO® design includes the variable speed pump and the VACUU·SELECT® vacuum controller with an external gauge head. The demand-responsive motor speed control on VARIO® models further extends the already long lifetimes of diaphragms and valves. And oil-free operation means that there is no risk of contamination from backstreaming.

Product features
• VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory
• Extraordinary diaphragm life for minimum operational and servicing costs
• Contamination-free pumping and evacuation
• High pumping speed, extraordinary ultimate vacuum and TURBO·MODE for use as backing pump for turbo pumps

With the help of high-quality Ohaus Frontier rotors and adapters, you can find the best solution for both basic and high-performance sample preparation needs.

The MV 10C NT VARIO select pump is an excellent solution for those who need high pumping speed and need fractional-millibar ultimate vacuum to work with high boiling point solvents even at low temperatures. Combined with the reliability born of its chemical resistant fluoropolymer and perfluoroelastomer wetted materials, this pump delivers reliable performance for floor-standing rotary evaporators, vacuum drying ovens, vacuum distillation columns, and other similar applications.
The integrated VACUU·SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary.
With VARIO control, the pump runs only as fast is necessary. This extends the maintenance intervals and makes the pumping unit whisper quiet

Product features:
• Ultimate vacuum with gas ballast: 1.2 mbar
• VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory
• Automatic boiling point detection and adjustment of the vacuum for short process times
• Ideal for evaporation of large amounts of high-boiling solvents even at low temperatures
• Extraordinary diaphragm life for minimum operational and servicing costs

The PC 3010 NT VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its combination of high pumping speed and fractional millibar ultimate vacuum, this pump is suitable for demanding applications with even high boiling point solvents at low temperatures. This pump is regularly used to support floor-standing rotary evaporators, vacuum drying ovens, distillation columns, and other similar work in miniplants, kilo labs, and scale-up facilities.

The integrated VACUU·SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary.

In addition, the VARIO control algorithm maintains the desired vacuum level by running the motor only as fast as necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection.
