VACUUBRAND PC 510 Select Chemistry Pumping Unit Ultimate Vacuum 7 mbar (5 Torr) Maximum Pumping Spe (more)ed 1.4 CFM at 60Hz Number of Heads/Stages 2/2 Features - VACUU·SELECT vacuum controller with graphical user interface simplifies work in the laboratory - Predefined applications save time and give reproducible results - Easy-to-use application editor allows own process sequences - Powerful vacuum pump with excellent chemical and condensate compatibility - Excellent environmental friendliness due to efficient solvent recovery Our PC 500-series chemistry pumping units of this series are an excellent choice for supporting electronically controlled evaporation or drying processes. Our popular MZ 2C NT two stage chemistry diaphragm pump is the heart of these pumping units, frequently used for medium-sized vacuum applications involving common solvents. 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 distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, it detects the boiling pressure and switches to two point control to hold pressure steady when a boiling point is detected. 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.INCLUDED: The VACUUBRAND PC 510 Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND PC 201 NT Chemistry Pumping Unit Ultimate Vacuum 1.5 mbar Max. pumping speed at 60 Hz 2 (more).2 cfm Number of Heads/Stages 4/3 Features - Outstanding chemical resistance and superior vapor tolerance - Exceptionally high performance even at low vacuum - Excellent ultimate vacuum even with gas ballast - Manual vacuum control, analog vacuum display - Excellent environmental friendliness due to efficient solvent recovery This chemistry pumping unit has a wide range of applications like evacuation, evaporation and pumping of gases and vapors in chemical, biological and pharmaceutical laboratories. Typical applications are rotary evaporators, vacuum concentrators and vacuum drying ovens with high boiling solvents. The manual flow control valve regulates the effective pumping speed at the vacuum connection; the vacuum manometer offers an analog vacuum display. The separator at the inlet (AK), made of glass with a protective coating, retains particles and liquid droplets. The exhaust waste vapor condenser enables near-100-percent solvent recovery.INCLUDED: The VACUUBRAND PC 201 NT Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MV 10 NT Diaphragm Pump Ultimate Vacuum 0.5 mbar Max. pumping speed at 60 Hz 6.1 cfm Nu (more)mber of Heads/Stages 8/4 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - Very low vibration - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuums. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. These pumps provide the advantageous combination of high pumping speed with an extraordinary good ultimate vacuum down to 0.5 mbar. The highly flexible, fabric-reinforced double diaphragms made of FKM offer extended operating life. Eight-cylinder NT pumps features quiet operation, smooth and easy to clean surfaces. Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. They generate a clean vacuum, as they are designed without any contact seals, hence no abrasion or dust is produced that might creep back into the application. Due to the outstanding ultimate vacuum, these pumps are often used as alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps. Additionally, the VARIO® design provides vacuum control by precise adjustment of the diaphragm pump´s motor speed. Depending on the application, the demand-responsive motor speed control results in unsurpassed lifetimes of service parts such as diaphragms, as well as optimal performance for backing of turbo pumps.INCLUDED: The VACUUBRAND MV 10 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
