Peristaltic pump for culture media preparation. Use it for serial dispensing of culture media, agar or any liquid diluent for efficient sample preparation.

Supplier: VWR Collection

Dual-head, dry running diaphragm pump for a wide range of laboratory applications. It pumps, compresses and evacuates without affecting media, i.e. media remains uncontaminated. The pump includes a diaphragm with patented tension optimisation, which allows the pump to be smaller prolonging the service life of the diaphragm.

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.

Dobbelthoved, tørkørende membranpumpe med indbygget selvtørrende system. Denne pumpe har en lang række anvendelsesuligheder i laboratorier, særligt hvor der er brug for rent vakuum og fugtige gasser skal pumpes væk. Eksempler omfatter drift af vakuumtørrekamre (til tørring eller varmebehandling af stoffer og komponenter), eller til dampsterilisatorer til sterilisering af instrumenter, beholdere, filtre og tekstiler. Denne pumpe kan anvendes i en lang række applikationer, på grund af dens høje modstandsdygtighed over for aggressive medier. Det innovative selvtørrende, system gør det muligt at blæse kondenseret væske ud af pumpehovederne ved høj hastighed under udpumpning. Vakuumet i modtageren forbliver konstant. Tørrecyklussen kan justeres i forhold til behovene ved den enkelte proces ved hjælp af tre variable. Efter tørring opnår pumpen et bedre vakuum, og kan udpumpe signifikant hurtigere end pumper uden et tørresystem.

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.
