Supplier: VWR Collection

Membranpump med två huvud och inbyggd självtorkningssytem som sätter färg på labbet. Passar för många olika applikationer speciellt när fuktiga gaser behöver evakueras till ex ihop med vakuumugnar (för torkning eller värmebehandling av olika substanser och komponenter) eller autoklaver för sterilisering av instrument, behållare, filter eller textilier. Med hög resistens för aggressiva medier. Tack vare patenterat membran (PTFE-överdraget) kan pumpstorleken minskas samtidigt som membranets livslängd ökar. Det innovativa torkningssystemet blåser ut den kondenserade vätskan ur pumpen med hög hastighet under evakuering. Vakuum förblir konstant. Torkningscykeln kan anpassas till varje process genom programmering av tre variabler. Efter torkning kan pumpen nå högre vakuum och evakuera snabbare än pumpar utan torkningssystem.

VCP 80 and VCP 130 can be used as vacuum and pressure pumps, and set a standard for efficient vacuum use. Use these pumps as an affordable vacuuming application where corrosion resistance is not required. These pumps can be used for vacuum filtration of aqueous solutions, or aqueous fumes including buffers, but are not recommended for pumping acidic, basic or organic fumes. These VWR® Collection vacuum/pressure pumps are designed for continuous unattended operation, and have two dial gauges with manual regulators that enable you to adjust and easily monitor the required vacuum or pressure level.

The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.
