Cole-Parmer Welch DryFast Vacuum Pump, PTFE, 2 torr, 25 L/min, 115V GO-79206-60

• Advanced Vapor Management System that increases pump life • All PTFE wetted materials • Perfect for high boiling point applications • Chemical duty • Convenient vacuum control • Easy operation and maintenance Use DryFast® vacuum pumps for precise, convenient solvent evaporations without oil mess. Portable and chemical resistant, DryFast PTFE diaphragm pumps provide excellent vapor flow and the right vacuum for top application performance. Perform rotary or centrifugal evaporations in minimal time with no sample foaming or bumping. DryFast pumps use Advanced Vapor Management (AVM) to adjust vacuum levels to exact levels needed for optimal evaporation rates. The handy AVM knob fine-tunes vacuum while purging condensates from the diaphragm to maintain efficient pumping and extended diaphragm life. |DryFast achieves top vacuum performance with only one or two pumping heads (model dependent) – a design that promotes efficiency and low maintenance. Quiet, oil-free, PTFE / perfluoroelastomer contact surfaces. 2 torr DryFast models provide deep vacuum for rotary evaporation of solvents with atmospheric pressure B.P. up to 160o C. The 35 L/min model will accommodate larger evaporation flasks up to 10L or small vacuum ovens. Use the 25 L/min model for flask evaporations to 2 L.
