Others: Electric aspirator pump


Portable dual-channel, water-jet aspirator pumps

VE-11 creates vacuum by an aspirator pump that is dependent on the vapor pressure of water; which, in turn, is a function of temperature. The lower the water temperature, the lower the potential vacuum. Ideal for rotary vacuum evaporator, decompressing distillation, vacuum drying, and vacuum filtering.

Model Name:
» VE-11(9.5L)

• Built-in circulating pump and water tank make these units portable and eliminate water waste
• Circulating pump continuously forces water across a set of aspirators - operating quiet, clean and efficient
• Included two metal venture aspiration jets to create the vacuum with a built-in check valve to prevent backflow of  water into the system
• Wetted parts: 304 stainless steel, polypropylene, silicone, and nickel-coated brass providing resistance against
