SKU: 202705

Welch, 202705, 1.7 l/min 1.8 Torr 1 Phase Self-Cleaning Dry Vacuum System

Complete oil-free dry vacuum systems for rotary evaporators and concentrators. Corrosion-resistant PTFE diaphragm vacuum pump systems enable superior control and efficiency for each evaporation. Provides controlled solvent stripping in flasks up to 5 L. Use 2 torr Model 2027 for solvents with atmospheric B.P. <160 C Degree- rapid DMF stripping at 4 ml/min. Includes digital gauge and vacuum regulation. Inlet and Exhaust separators protect pump and lab atmosphere.

Features:

  • Automatic Self-cleaning purge maintains efficiency, extends diaphragm life
  • Free air displacement: 35 L/min (1.2 CFM)
  • Incremental ballast switch enables fast response to bumping / foaming

Applications:

  • Controlled vacuum for Rotary evaporators
  • Centrifugal concentrators, and other evaporative processes.
Applications Controlled vacuum for Rotary evaporators, Centrifugal concentrators, and other evaporative processes.
