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.

• High chemical resistance and therefore ideally suited for pumping aggressive gases and vapours.
• Short process times and smooth running due to optimal setting of the pressure via the VACUU·SELECT controller.
• The VARIO^® technology controls the vacuum precisely and efficiently via motor speed.
• Power consumption, maintenance and noise are exceptionally low.
• The outlet catchpot and solvent condenser combine to prevent solvent vapor emissions into the lab, allowing for nearly full recovery of solvents.

Country-specific power cord versions available on request.

For non-magnetic coatings on iron and steel and coatings on non-magnetic metals. The Offset-Accur function allows you to adjust the instrument precisely on the locally measured range by a two-point calibration. This results in a higher accuracy of approx. 1 % of the measured value.

• LCD display, backlit
• Scan mode allows continuous measurement or single point measuring mode
• Mini Statistics Kit: displays the measured result, the average value and the max and the min value
• Internal memory up to 99 values
• Selectable measuring units: µm, inch (mil)
• Data interface RS-232

Scope of supply:
Coating thickness gauge, external sensor, base plate, calibration foils, carrying case

Precision
Standard:	3 % of measured value or ± 2,5 µm
Offset-Accur:	1 % of measured value or ± 1 µm
Minimal base thickness:	0.3 mm

Fully equipped vacuum controller with capacitive, gas type-independent absolute pressure measurement using an alumina-ceramic diaphragm. While the base unit Vacuum Controller VACUU·SELECT^®still requires a separate vacuum control valve as an accessory, there is the fully equipped Compact controller VACUU·SELECT^®as two-point vacuum regulator with chemical suction line valve.
With connected vacuum valve the VACUU·SELECT^® automatically detects the boiling point during solvent evaporation and switches to two-point control mode. The graphical user interface offers predefined vacuum processes for all common laboratory applications. Applications, such as desired vacuum and other parameters can also be put together and controlled individually.

• Interactive, graphic touch display for easy operation
• Touchscreen display can be operated with safety gloves
• Predefined vacuum processes for reproducible results and time savings in the laboratory
• Fully automatic evaporations at the touch of a button
• Easy-to-use application editor for creating your own processes
• Integrated help function
• Integrated ventilation valve also for inert gas
• Ethernet/USB (Type A) interface
• EX approval: II 3/- G IIC T4 X Internal Atm. Only

Fully equipped two-point vacuum controller with capacitive, gas type-independent absolute pressure measurement using an alumina-ceramic diaphragm. Available as benchtop or stand version and ready to use due to standard laboratory connections.
