Light obscuration particle counters

7 listings from 6 suppliers · 2 Japanese makers

Light obscuration (LO) counters size and count particles one by one from the amount of laser light each particle blocks. LO is the first method in the particulate matter tests for injections in USP <788> and the Japanese Pharmacopoeia (JP 6.07). Buyers compare which compendial methods the software runs, the sample volume per test, the size range and maximum concentration, electronic records under 21 CFR Part 11, and handling of viscous samples. This page lists the products we track and their makers.
