You Searched For: Vacuum Diaphragm Pumps

Supplier: VWR Collection

Description: 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.

Catalog Number: (181-0310)

Supplier: VWR Collection

Description: 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.

Supplier: VWR Collection

Description: 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.

Catalog Number: (181-0094)

Supplier: VWR Collection

Description: Dual-head, dry running diaphragm pump with an integrated self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and moist gases must be pumped down. Examples include operation of vacuum drying chambers (for drying or heat-treating substances and components) or steam sterilisers for sterilising instruments, vessels, filters and textiles. This pump can be used in a wide range of applications due to the pump's high resistance to aggressive media. The pump includes a PTFE coated diaphragm with patented tension optimisation, which allows the pump to be smaller, and prolongs the service life of the diaphragm. The innovative self-drying system allows condensed liquid to be blown out of the pump heads at high speed during evacuation. The vacuum in the vacuum chamber remains constant. The drying cycle can be adjusted to the requirements of the individual process using three variables. After drying, the pump reaches a better vacuum and is able to evacuate significantly faster compared with pumps without a drying system.
