The BUCHI Vac V-700 Vacuum Pump is an oil-free, chemically resistant PTFE diaphragm vacuum pump designed for laboratory vacuum generation. The unit shown in the photograph is clearly identified as BUCHI Vacuum Pump V-700.

The V-700 is designed for pumping laboratory gases and vapors and is particularly suited to applications such as rotary evaporation, vacuum drying, laboratory distillation, and vacuum filtration. BUCHI specifies a pumping capacity of approximately 1.8 m³/h and an ultimate vacuum of less than 10 mbar.

The pump uses a dual-head diaphragm configuration with chemically resistant materials including PTFE, PEEK, glass, and FEP. Its oil-free design helps avoid contamination associated with oil-lubricated vacuum pumps and makes it suitable for solvent-related laboratory applications.

Applications

The BUCHI Vac V-700 can be used for rotary evaporation, vacuum drying, laboratory distillation, vacuum filtration, solvent processing, and general laboratory vacuum applications. It is especially suitable for use with laboratory rotary evaporators and compatible BUCHI vacuum systems.

The pump can also be integrated with compatible vacuum controllers, secondary condensers, cold traps, Woulff bottles, and other vacuum-system accessories. The exact accessories shown or supplied with this particular unit should be confirmed separately.

Benefits of Refurbished Laboratory Equipment

Refurbished laboratory vacuum pumps can provide laboratories, research facilities, educational institutions, and industrial users with access to established vacuum technology at a lower acquisition cost than new equipment. The BUCHI V-700 is particularly useful for laboratories requiring clean, oil-free vacuum for evaporation, drying, distillation, and filtration.

Before use, the pump should be professionally inspected and tested for diaphragm condition, valve condition, vacuum performance, electrical safety, connections, and operating noise. The photograph shows significant external cosmetic wear, so the actual operating condition should be verified independently.

Additional Information

The photographed unit is clearly identified as a BUCHI Vac V-700. The photograph does not show the complete rear rating plate, so the exact electrical configuration and accessories supplied with the unit should be confirmed before purchase.

BUCHI lists compatible accessories including vacuum controllers, secondary condensers, secondary cold traps, and Woulff bottles. These accessories are not assumed to be included unless specifically stated in the product package.
