Designed to fully meet the regulation of vacuum as defined in ‘The Microbiology of Drinking Water (2002)¹

Membrane filtration of water and sewage or sludge using vacuum pumps has been well established in Bacti and Chemistry laboratories for many years. However, for certain methodologies it is well documented that the vacuum level should be strictly controlled such that technician "apply a vacuum not exceeding 65 kPa (500 mm of mercury) and filter the sample slowly through the membrane filter”

Most vacuum pumps or central vacuum systems used in laboratories are designed to produce a much greater vacuum level than that required. In order to ensure complete compliance with the methods vacuum requirements, West Technology Systems has developed the Laboratory Vacuum Regulator.

The Laboratory Vacuum Regulator simply connects in-line with the existing vacuum pump or system and allows the technician to easily monitor and adjust the vacuum level to 500 mm of mercury. The unit can be either bench mounted or wall mounted.
The Laboratory Vacuum Regulator is available with either a digital vacuum display or an analogue vacuum display.
