Sieve shakers are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. Prevest Research Institute is having an analytical Vibratory sieve shaker model: AS 200 Digit from from Retsch. This is having a controllable electromagnetic drive for optimal adaption for every product. Fractions are obtained after short sieving times and are having options for controlled amplitude, digital display of vibration height and time and interval operation as required. Application examples include separation, fractioning and particle size analysis of dental cements, bioceramics, bioglass, metals powders, minerals, plastics, etc. this can measure in the range from 20 μm – 25 mm using a series of standard sieves. Dry as well as wet sieving is also possible using the instrument.
