These laboratory sieve shakers are suitable for research and development, quality control of raw materials, intermediate products and end products, and production control. Sieve shakers are designed for grain size determination, separation, and fractionation of powders, bulk goods, and suspensions. They work at exactly 3,600 oscillations per minute and feature exact, reproducible results according to DIN 66165. They also have high load endurance, extremely quiet operation, and short sieving times with exact separation. Sieving machines feature a maintenance-free electromagnetic drive and three-dimensional movement of the sieve stock due to the tilted spring arrangement. The vibration height can be set infinitely from 0–3mm. These machines are suitable for both wet and dry sieving, and meet all ergonomic requirements for a modern laboratory. CE marked. The AS 200 control model features digital time, interval, amplitude, and acceleration display. All sieving parameters are displayed on screen before and during the sieving process, enabling user control at all times. The AS 200 control model can be calibrated, ensuring 100% reproducibility of sieving results, even from one AS 200 control unit to another. The sieve mesh acceleration g setting enables the AS 200 control to work with congruent acceleration. Serial interface for control via PC. The AS 200 digit model features a digital time display and interval operation, as well as analog setting and optical control of the vibration height. The AS 200 basic model features the setting of time and vibration height by potentiometer, and optical control of vibration height. It is economical and capable of handling easy materials and occasional sieving tasks. Also available are three types of clamping units. Deluxe unit 14214-622 offers a view cover, smooth rods, and quick action clamps. The cover stays on the rods and the sieve stack may be removed. Standard set 14214-620 offers a view cover, threaded rods, and clamping nuts. Economy clamp set 14214-618 is a stainless steel cover, with threaded rods and clamping nuts. Available test sieves for AS 200 laboratory sieving machines offer 15% less weight than traditional sieves and also a larger sieving surface. They feature a long-lasting taut mesh, high corrosion resistance, and easy cleaning due to high-grade alloy stainless steel. The mesh is electro-welded into the frame, eliminating any possible solder or epoxy contamination
