Description
This Used TOPAS EMS 755 electromagnetic sieve vibrator is designed for high-precision sieving of both dry powders and wet suspensions, particularly in the fine micron range. Delivered with 4 analytical 50 µm sieves, it offers both horizontal and vertical oscillation of the sieve clamp to promote efficient particle separation. The device is mountable on a laboratory stand and allows for controlled amplitude adjustment to optimize sieving dynamics.
