The precise measurement of "nothing" since 1970
It is with our passion for precision that we support our customers with their vacuum applications. Vacuum allows a great variety of manufacturing processes. The same large field of applications is served by our vacuum products. Included applications are for example process industry, coating, analytics and R & D as well as semiconductor and solar.
Freeze drying is a method for carefully extracting moisture from products like food or serums. Such products are sensitive to temperature and care has to be taken in order to protect their internal structure. Freezing is followed by an accurately controlled pressure decrease, which leads to sublimation of the microscopic ice crystals.
Losses of expensive product lots must be avoided and process run at reasonable cost. This is why the demands on the required vacuum gauges regarding repeatability and reliability are extremely high.
The VSP63MV Pirani is protected against vapor condensation by a stainless steel shield. Its metal sealed sensor with long-life helix filament and the stainless steel flange make the gauge especially robust. The results are an improved reliability of the process and a decrease of maintenance costs.
One of the world´s leading companies in the field of development and production of freeze dryers has trusted in the quality and precision of our vacuum sensors for many years.
