The VACUUBRAND laboratory pumping unit PC 3 is designed for fine vacuum generation especially for application in a chemistry laboratory: efficient, easy to operate, compact. The PC 3 offers an experience based combination of useful and efficient components to make work easier and to overcome typical problems.

The pumping unit is equipped with a two stage rotary vane pump (from the series RZ 2, RZ 5, RZ 8 or RZ 16) at the user's choice. High water vapour capacity and ease of maintenance, excellent ultimate vacuum even with gas ballast. The rotary vane vacuum pump is protected by the glass cold trap GKF 1000i. The GKF 1000i is vacuum insulated and silver anti-reflection-coated and provides therefore an increased coolant lifetime. For a higher degree of safety, the GKF 1000i is protected against external damage and implosion by a shield. The PC 3 is an extremely compact and light system for easy handling. It is supplied with an inlet butterfly valve, gas ballast, an exhaust oil mist eliminator and a vacuum gauge port. The pumping unit is shipped ready for use.
