Vacuum Pumps Rotavac Valve Tec

Suitable for all Hei-VAP Rotary evaporators. Vacuum can be controlled manually or via valve operated vacuum controllers.With two-stage diaphragm pumpAll components which come in contact with media are built from chemically resistant fluoropolymerThe durable PTFE design guarantees an superior diaphragm lifespanThe head cover and clamping disc have a stable core made of metal which offers unsurpassed long-term performance of your operational parametersThe direct pump drive (without belt) is exceptionally quiet, creates a very low vibrational environment and reduces the need of wear and tear parts to a minimumThe gas ballast valve has been optimized to prevent media condensing in the pumpThe pumps can be combined with a condenserFor combination with the Hei-VAP Precision Rotary evaporators a vacuum valve is necessary.High suction capacity for fast evacuationSuction capacity for up to 3 rotary evaporators at the same timeDepending on your application you can switch on and off the vacuum pump via switchbox

Suitable for Rotary evaporators Hei-VAP series. Controllable vacuum pumps for digital regulation of the vacuum via operation panel or directly at the unit.High distillation rates and reduced process time by 30 %.Solvent recovery up to 99 %.Pump stops automatically as soon as the set vacuum is reached and reliably holds the vacuum constantIncreased diaphragm performance life due to periods of non-operationLow energy consumptionSignificant noise and vibration reductionThe pumps can be combined with a condenser3-stage diaphragm pumpHigh suction capacity for fastest evacuationEven if the gas ballast valve is open an excellent ultimate vacuum is reached when working with easily condensable vapors. This makes distilling high boiling point solvents such as DMF or DMSO possible at low bath temperatures

Suitable for Hei-VAP Core. Fully controllable stand-alone pumping unit including vacuum controller3-stage diaphragm pump is made from chemical-resistant materialHigh suction capacity for fast evacuationPrecise vacuum control avoids bumping and eliminates foaming of your evaporation solutionAutomatic vacuum supply to the process parametersThe pump unit can be combined with a condenser

Includes secondary condenser and air intake separation vessel. This vacuum system can be applied in many different fields in order to evacuate, evaparate and pump out gases and vapors. Thanks to the emission condenser it is possible to achieve a chemical recovery of almost 100%.Excellent compatibility with chemicals and condensateExcellent ultimate vacuumVery quiet and very low VibrationVery high suction capacity of 50l/min
