Air-jet sieve shaker 200 LS-N is an analysis-sieve shaker with advanced features. For lab work requiring highly exact, reproducible sieve analyses. The clearly organized membrane keypad ensures ease of operation. Extraordinarily good dispersing of the sieved material by the air jet enables measurements down to 10 μm with micro-precision sieves. The 200 LS-N is the successor model to the Alpine air-jet sieve, model 200 LS; which was manufactured for more than 30 years. Analysis range20 μm to approx. 4000 μm for work with analytical test sieves with diam. 200 mm 10 μm to 30 μm for work with micro-precision sieves with diameter 75 mm.
