VACUUBRAND VARIO® chemistry pumping unit PC 3004 VARIO select

VARIO® pumps and pumping stations control the vacuum precisely via the speed of the vacuum pump. The MD 4C VARIO select serves as the basic pump. It offers high pumping speeds and meets laboratory vacuum requirements for most high-boiling solvents. The PC 3004 VARIO select offers a proven concept for evaporation of large quantities of solvents. With its graphical user interface, the integrated vacuum controller VACUU-SELECT offers predefined vacuum processes for all common laboratory applications. In solvent evaporation, the boiling pressure is automatically detected and adapted to the process. Of course, application, desired vacuum and other parameters can also be individually configured and controlled. With VARIO control, the pump does not run faster than necessary. This extends the maintenance intervals and makes the pumping station whisper quiet. The suction-side separator made of glass with protective coating retains particles and droplets. The emission condenser on the discharge side enables almost one hundred percent solvent recovery for active environmental protection.

Performance features
