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.
