  • Application Area: Use for air sensitive synthetic chemistry, in combination with a vacuum manifold (Schlenk line)

"In our lab, we have 2 RZ6 rotary vane pumps from Vacuubrand that we use for air sensitive synthetic chemistry (synthesis of catalysts etc) in combination with a dual argon/vacuum manifold. Those pumps provide a rapid and very high vacuum (10-3 mbar) even with gas ballast (lower than 1.10-1 mbar) and an excellent pumping capacity that make them very efficient for our applications: degasing of solvents, working under air-free conditions etc. Furthermore, they are very quiet, with low vibrations, which is ideal for prolonged use (around 5 hours every day). We particular recommend their use with the dedicated oil mist filter and shut valve VS 16. After 2 years of intense running with solvents, there is absolutely no sign of corrosion or loss of performances. They are finally very easy to use and to service, and cheaper than the competition (Edwards), so basically the best value rotary vane pump on the market. "

RZ 6 Rotary Vane Pumps from Vacuubrand

These powerful rotary vane pumps feature an unusually compact design and low weight for pumps of this capacity. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium to increased gas flow rate. The PC 3 rotary vane pumping unit, with GKF 1000i cold trap at the inlet, helps the pump handle large amounts of condensable vapors. The PC 3 pumping unit is compact, user-friendly, and well-arranged, with an oil mist filter at the outlet, a valve, and a T-connection for a gauge. Various packages including pump, oil mist filter, etc. are available.

Rotary vane pumps are used where an ultimate vacuum between a few mbar and down to 10-³ mbar has to be attained. Typical applications are degassing, lyophilization, fine vacuum distillation, and drying chambers. The pumping unit PC 3 is the perfect choice for applications requiring special protection of pump and environment. Designed for the use in chemical laboratories, the cold trap helps the pumps handle large volumes of condensable vapors. The cold trap is metalized for extended coolant life and protected against implosion.

Performance features:

  • high flow rates even at vacuum levels approaching ultimate vacuum
  • high water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast
  • vacuum-tight at switch-off; external anti-suckback valve not needed
  • large oil volume: Long intervals between oil changes
  • ease of maintenance due to telescopic design
