New pumping units with electronic vacuum controllers
The generation of vacuum in the laboratory: the diaphragm vacuum pumps, thanks to their chemical resistance, oil-free operation and the feature to recuperate the solvents, are the number one among the present technologies of vacuum systems. Together with the vacuum controller CVC 3000, VACUUBRAND offers three categories of vacuum systems. During the ACHEMA 2009 VACUUBRAND presented the new series, which have different specifications in the final vacuum and the type of control. The series 500 and 600 are the classical two point vacuum regulators. The series 600 reaches a final vacuum of 1.5 mbar, and is, above all, predestined for an application with solvents of a high boiling temperature. Both series offer models suited to handle two simultaneous processes with a single pump. The vacuum systems from the series 3000 VARIO operate with a regulation, that controls the rpm of the motor, and allow the automatic detection of the boiling point during the entire process until the full evaporation. Depending on the typ of installed pump, a final vacuum of down to 0.6 mbar may be achieved. Due to the internal seals, the units achieve y excellent pressure tightness. These pumps are especially silent and generate only extremely low vibrations, due to the patented "flying motor". Cleaning and care is very easy because of the new and compact design and the smooth surfaces. The new polypropylene casing, of low flammability, is in accordance with the laboratory guidelines, and is designed for applications where especially aggressive media, gases or solvents, are used.
