In addition, we also offer the software package LS-PRO 5.0 as per 21 CFR part 11. The factory specifications of many of our customers specify the air jet sieve as the test equipment, whereby individual settings for sampling, sample preparation, batch weight, underpressure, sieve selection, sieving time, dispersing agents, sieve cleaning, air humidity, and temperature are defined for each and every product. In each and every case, the Alpine Air Jet Sieve 200 LS-N guarantees a high degree of reproducibility of the achieved results.     © 2003-2010 HOSOKAWA ALPINE – all rights reserved –
