The Chemistry Vacuum Pumping Unit PC 8 / RC 6 incorporates the Chemistry Hybrid Pump RC 6 (Cat. No. 9.882 235). It achieves an ultimate vacuum in the 0,0004 mbar range and is used for demanding vacuum applications such as freeze drying, drying chambers, concentrators, etc. The RC 6 provides the vacuum performance of a two stage oil sealed rotary vane pump. The chemistry diaphragm pump evacuates the oil reservoir of the rotary vane pump and prevents- under intended operating conditions- the condensation inside the oil-filled section. Any condensation inside the oil-free diaphragm pump is much less problematic. Items supplied: Pumping unit completely mounted, with Chemistry Hybrid Pump RC 6, insulated exhaust vapour condenser,condensate catchpot on pumping unit console, on/off switch, cable with plug and instructions for use.
