Chemically resistant membrane pump for Hei-VAP Expert Control and Hei-VAP Ultimate Control devices. The vacuum can be controlled by changing the speed of the pump, enabling constant distillation conditions and shorter operation times.
• Recommended for solvents with low or medium boiling points
• Condenser is not in scope of delivery

The VARIO® select DUO pumping units are consisting of a combination of two individual VARIO® pumping units, connected in parallel on the suction side and driven synchronously by one vacuum controller VACUU•SELECT.

The vacuum is controlled accurately. The speed of the two individual pumps is exactly adjusted to the vacuum needs. The controller allows both fully automatic distillations without any user pre-settings as well as specific and reproducible program sequences. The integration into existing control systems via digital and analog interfaces is also possible. The consequent design to highest chemical resistance provides the ideal prerequisite for universal use in chemistry and pharmacy - without any operating fluid such as water or oil.

Performance features
• automatic adaptation of the vacuum level throughout the process for high process reliability and unattended operation
• short process times due to powerful vacuum pump and accurate (hysteresis-free) vacuum control, even for large amounts of steam
• removable vacuum controller VACUU•SELECT, variable to arrange, easy to use with multilingual full-text menus, simply integratable by digital or analog interfaces
• unmatched diaphragm life with minimal operating and maintenance costs
• excellent environmental friendliness due to minimized energy consumption, no operating fluid needs (oil, water) and efficient solvent recovery

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.

Holder rack For injector module A 620.
• Arrangement: 2 x 5 fields
• The holder rack enables laboratory glassware to be positioned ideally for the best possible cleaning results. The glassware is also protected against damage.
• Part of the EasyLoad system
The EasyLoad system makes reprocessing laboratory glassware considerably faster, simpler and more reliable. The biggest benefit afforded by the new system is that load items can be positioned over nozzles both more simply and faster as height adjustment of the holders is no longer necessary thanks to the smart combination of nozzles and holding frames. This makes correct positioning extremely easy.

This three-stage diaphragm pump is a powerful solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1.5 mbar. 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 MD 12 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 and excellent ultimate vacuum and TURBO·MODE for use as backing pump for turbo pumps

• Required to control vacuum for Hei-VAP Control models with valve-controlled vacuum pumps.
• Can be positioned for easy access and cleaning.
• Not required for manual vacuum control
