Laboratory Test Sieve is a measuring instrument and should not be maltreated. Sieves should be used with care, cleaned regularly and stored in a safe dry place. Care should be taken when sieving certain chemicals, especially hygroscopic salts, which can affect brass sieves. Always wash and dry the sieves after each test. For the sizing of substances which are liable to corrode brass, we recommend the use of stainless steel sieves. Particles should never be forced through a test sieve - even the gentle brushing of material through the finer meshes is undesirable, but this procedure is occasionally unavoidable for certain materials that are otherwise difficult to sieve.
Test sieve available in diameter 12', 8', 300mm and 75mm with stainless steel frames in all kinds of stainless steel wire cloth and copper mesh, nickle-plated, suitable for precision testing and sorting of abrasive.
300mm test sieve is produced by the standard ISO3310-2:1990. The aperture sizes are from 3.35mm to 0.038mm. The frames and covers are made of stainless steel while the wire cloth is in all kinds of material such as brass, bronze, stainless steel and copper.
75mm test sieve is available in apertures sizes from 500 micro to 5 micro, with allowance +2 micro, in accordance with the standard ISO3310-3:1990. The screen is electroformed, and its frames and covers are made of quality stainless steel.
It is mainly used for precise classification of the minute granule materials and It is widely used in metallurgy, abrasive, construction industries and research lab.
Other special apertures can be customized.
