Our universal sample holder can measure any 5 - 40 mm diameter disk and is available on all systems. This holder can also be used for large thicknesses, even up to 1 cm material. The connection is made through the quick connector as with the normal sample holders. As the stainless steel universal sample holder stands aside the instrument, it is easier to clean than the regular holders. This facilitates more the use of dirty water, highly viscous oils and such as wetting liquids for actual filter testing. For safety reasons, the total pressure is limited to 10 bar.
