About Welch 2042B-01 Vacuum Pump, PTFE, 2 Torr, 35
Use dry fast vacuum pumps for precise, convenient solvent evaporations without oil mess. Portable and chemical resistant, dry fast 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. Dry fast 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. Dry fast 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 tort dry fast models provide deep vacuum for rotary evaporation of solvents with atmospheric pressure b.p. Up to 160O C. The 35 L/min AO-79206-50 will accommodate larger evaporation flasks up to 10L or small vacuum ovens. Use the 25 L/min AO-79206-50 for flask evaporations to 2 L. 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.
