These convenient KNF filtration pumps are lightweight and easy to use in your lab. With KNF pumps, there are no metal wetted parts within the pump heads to corrode, assuring long life. Don't settle for other brand's "standard duty" models. KNF's patented multi-port valves increase performance and
tolerate occasional liquids drawn into the system without damage. An optional, factory installed vacuum gauge and regulator package (pictured below) provides simple, convenient control over your vacuum process.
