They feature fully automatic evaporation control on the push of a button. The basic pump is the three-stage MD 4C NT VARIO chemistry diaphragm pump which meets high vacuum requirements for most high boiling solvents. The PC 3004 VARIO offers a well proven choice for evaporation of large amounts of solvents. The separator at the inlet, made of glass with protective coating, retains particles and liquid droplets. The waste vapor condenser at the outlet enables near-100-percent solvent recovery, efficient recycling and active environmental protection. The on-demand motor speed control results in unsurpassed lifetimes of service parts, such as diaphragms.\u003c\/p\u003e\u003cp\u003e   Vacuum controller  CVC 3000   Number of heads \/ stages  4 \/ 3   Max. pumping speed m3\/h 4.6   Max. pumping speed cfm 2.7   Ultimate vacuum (abs.) mbar\/torr 1.5 \/ 1.1   Ultim. vac.
