Onsite Laboratory

Our onsite laboratory analyses raw materials, in process and finished solutions, providing our customers with certified products. Our products are tested to multi-compendia (USP, EP, JP, NF, BP, FCC) and certificates of analysis provided to our customers.


Our Production Plant

Micro-Bio has been operating our electrolytic membrane cell process for over 40 years. We were the first commercial membrane cell plant in Western Europe and are the experts in this field. The membrane process is the BAT (Best Available Technology) for the production of High Purity Sodium Hydroxide, Hydrochloric Acid and Sodium Hypochlorite. A recent multi million euro investment in the latest electrolysis technology keeps us at the forefront of the industry. This investment has led to a reduction in our energy consumption. This coupled with our 100% renewable energy aligns with ours and our customers sustainability goals.
