Self-Cleaning Vacuum System w/ North America Plug

Welch, 202501, Self-Cleaning Vacuum System with North America Plug 115V, 1.7(28) Ultimate PressureComplete 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 9 torr Model 2025 for solvents with atmospheric B.P. <120°C. Includes analog gauge and vacuum regulation. Inlet and exhaust separators protect pump and lab atmosphere.FeaturesAutomatic Self-cleaning purge maintains efficiency, extends diaphragm lifeFree air displacement: 35 L/min (1.2 CFM)Incremental ballast switch enables fast response to bumping / foamingApplicationsConcentrator - Gel Dryer CombinationGet top utility from your vacuum pump! Selecting a pump with proper flow and vacuum specifications will enable you t°Configure a manifold to dry samples in your centrifugal concentrator or dry gels. Use of a cold trap is recommended.Rotary EvaporatorRotary evaporators are typically used to remove solvents following chemical reactions. Combined with gentle heat from the evaporator bath, controlled vacuum is used to bring solvents to boiling or near-boiling. Efficient solvent distillation requires vacuum balanced to achieve sufficient pressure reduction and molecular flow w/o losing sample or overrunning the condensing capabilities of your rotovap.
