ELECTROMAGNETIC VIBRATORY SIEVE SHAKER SIEVEA 502 Electromagnetic Vibratory Sieve Shaker is designed and manufactured to meet higher requirements for sieving in the lab.The instrument is in fact a sieve shaker in the lab.It consists of sieve base, electromagnetic generator, sieve holder and standard test sieves.SIEVEA 502 uses electromagnetism as driving force, distribute the powder uniformly throughout the screen,and do three-dimensional oscillation at the same time.This particular vibratory method effectively prevents the blockage of sieve holes by near-sieve particles. So that the undersize particles can effectively passed the sieve. According to the particle size grade numbers the user can choose standard test sieve with different mesh size.The sieving instrument has higher work efficiency and less noise, and is widely used in medicine, food and chemical industry etc.SIEVEA 502 test sieve shaker fully conforms to European Pharmacopoeia Ph.Eur. 2.9.38.
