Keofitt ® has developed sterile sampling valves for all industries concerned with sanitary product quality like pharmaceutical, brewing, beverage and food industries.

The patented Keofitt ® Membrane Sampling Valves are designed for physical, chemical and microbiological sampling. With a wide range of sterile sampling valves and various accessories this sterile sampling system is outstanding on the market and are "3A", "FDA" and "EHEDG" certified.	Video
Operation principle : The principle in the Keofitt ® Sterile Sampling System is the possibility to sterilize the valve after every sample, and continuously to have at disposal an aseptic representative of the media to be tested. Open valve : sampling Closed valve : Sterilizing
