In ISO standard cleanroom environments in the pharmaceutical, life sciences and manufacturing industries, airborne particles can be a major source of contamination. Not only can they cause yield loss, the particles can also lead to corrosion and product degradation. ISO standards and cGMP regulations for air purity require complaince by presenting consistent results that can be verified on a regular basis. Because of these requirements, we recommend our Colorex and Sphera SD/EC ranges. Suitable products are Colorex SD, Colorex EC, Colorex Plus EC, Sphera SD and Sphera EC.
