Testing in a cleanroom (class A in B) requires extensive equipment. Labor LS conducts the tests in one of the most modern cleanroom testing facilities in Europe (commissioned first quarter 2017). Right from the start, planning of the plant was devoted to modern and lean processes, the benefit for our customers and capacities designed for growth. Owing to state-of-the-art cleanroom technology, numerous redundant systems from energy to nutrient media supply, optimised process steps in sample preparation and the introduction of samples and personnel, Labor LS can offer a high standard of testing and process reliability. This test environment also allows test samples with large volumes and preparations whose primary packaging materials are not H2O2-tight to be tested quickly and efficiently.
