VARIO select THE NEW CHEMISTRY VACUUM PUMPS easy, efficient and extremely durable

VARIO select chemistry vacuum pumps easy, efficient and extremely durable The combination of speed controlled VARIO chemistry diaphragm pumps and the new VACUU·SELECT vacuum controller makes the VARIO select chemistry pumps the ideal solution for chemical processes that require precise vacuum, such as rotary evaporation, vacuum drying or vacuum concentration. Thanks to their uncompromising chemical resistance, VACUUBRAND chemistry diaphragm pumps are ideally suited for pumping aggressive gases and vapours. With the VACUU·SELECT controller setting the optimum process pressure becomes a...

Unsurpassed long-term performance VACUUBRAND® Quality VARIO Control VACUUBRAND chemistry diaphragm pumps offer unsurpassed long-term performance – even in demanding conditions. Thanks to high-quality fluoropolymers, precise manufacturing processes, and 100 % quality control, VACUUBRAND chemistry diaphragm pumps guarantee uncompromising chemical resistance, long service intervals, and longstanding reliability. Efficient and whisper quiet VARIO-pumps provide pinpoint vacuum control by adjusting the motor speed. This guarantees optimal process times and reproducible results. VARIOpumps run on...

VACUUBRAND® Quality Uncompromising chemical resistance Proven chemical resistant materials glass touch panel display ceramic vacuum sensor chemical resistant wetted materials: Pump chamber of a chemistry diaphragm pump Well-proven PTFE sandwich diaphragms for increased reliability and extended service life. Valve connectors are made of ECTFE for an optimum of thermal, mechanical and chemical resistance. Inlet and outlet flapper valves are made of FFKM or PTFE for both highest leakage tightness and best chemical resistance. Acid amides Acids, dilute or weak Acids, strong or concentrated...

VACUUBRAND® Quality The VACUUBRAND stability core principle Unsurpassed long-term performance The unique stability core design of high-stress components - such as the head cover and diaphragm clamping disc - ensure reliable performance over the long term. The stability core is created through a multi-step manufacturing process which creates a thick layer of fluoropolymer wetted material. Together with the perfluoroelastomer valves and seals, these materials provide outstanding chemical resistance and minimal surface adherence. This prevents the degradation of the pump from chemical...

VARIO® Control Precisely optimized vacuum VARIO pumps combined with the VACUU·SELECT controller deliver unparalleled precision, free of hysteresis. Pumping speed automatically adjusts in real-time to optimize gas flow based on the rate of evaporation or gas load, and the system volume. VARIO control always seeks to optimize process conditions and minimize process time. Classic 2-point vacuum valve control Pinpoint VARIO control via motor speed control pressure VARIO® time control by opening and closing a vacuum valve control via motor speed of the pump pump always runs at full speed pump...

VARIO® Control Whisper quiet operation The patented new drive system of our chemistry diaphragm pumps guarantees extra quiet, ultra-lowvibration operation. Due to the VARIO control, the pump runs at a significantly reduced speed making the pump whisper quiet. Reduced power consumption and long service intervals In comparison to vacuum pumps with constant motor speed, power consumption is reduced by up to 90 % during laboratory operation. The intelligent VARIO motor speed control minimizes wear on the pumps. The already long diaphragm life time of approximately 15.000 working hours is...

VACUU·SELECT® Controller Intuitive user interface Using the VACUU·SELECT controller is just like using a smartphone. Interactive menus designed specifically for lab applications get you up and running in no time. application-based navigation integrated contextual help function with application-specific tips choose from 14 languages Ready to use vacuum procedures for all common applications VACUU·SELECT includes predefined vacuum procedures for all common lab applications. The process steps and control parameters can easily be adjusted to suit any application. It‘s as simple as pick your...

VACUU·SELECT® Controller Fully automatic evaporations at the touch of a button Automatic evaporation mode is perfect for controlling applications like rotary evaporation or vacuum distillation. Simply press the start button and the boiling pressure will be detected automatically. As needed, adjustments are made automatically until the process is complete. This makes the process run quickly, and without foaming. There‘s no need for manual adjustments or constant babysitting. Easy customization through drag and drop editing Use the new drag and drop editor to adapt the predefined processes...

Product range From laboratory to mini-plant VACUUBRAND offers the VARIO chemistry diaphragm pump technology for a wide range of operations. Models with pumping speeds ranging from 2 m3/h to nearly 20 m3/h support applications ranging from individual laboratory applications such as rotary evaporators, to multi-user lab vacuum networks, to replacement of rotary vane pumps in kilo labs and pilot plants. Available pump models offer ultimate vacuum ratings between 70 mbar and even down to 0.6 mbar. Select the right pumping unit for evaporation of your low- or high-boiling-point solvents at low...

Product range The right VARIO®-Pump for your application Rotary evaporators / reactors The PC 3001 VARIO select is ideal for vacuum applications with high boiling solvents. The hysteresis-free vacuum control prevents superheating and foaming to protect valuable process samples. The controller enables automatic detection of vapor pressures and automatic adjustment of the vacuum level to the process requirements. For large evaporation flasks (> 5 l), the PC 3004 VARIO select with a max. flow rate of 4.6 m3/h is ideal for handling large quantities of vapor in a short time. Vacuum drying...
