About Biosan

microbiology laboratory


Biosan Laboratories is an environmental microbiology laboratory that was founded by Dr. Harold Rossmoore in 1973. Our initial microbiology lab was in Ferndale, MI where we remained until 1994. Since we knew many of our lab customers would benefit from the ability to perform microbiology testing on-site, Biosan developed the following bacteria and fungi test kits: the Sani-Check AB for detecting bacteria, the Sani-Check YM for detecting fungi, the Sani-Check SRB kit for detecting anaerobic sulfate reducing bacteria.

Microbiological Test Kit Manufacturing Facility

In response to our clients’ needs, we developed an agar based detection method known as a dipslide for microbiological testing. In 1994, we moved to a 6400 square foot building in Warren, Michigan and added a 3600 square foot manufacturing area in order to expand our manufacturing capacity. Today our production department is dedicated to making high quality agar dipslides for the microbial testing of a variety of industrial fluids.

Our highly experienced microbiologists provide antimicrobial testing services for a variety of industries including textiles, plastics, paints, inks, metalworking fluid, and water treatment (legionella testing) using ASTM, AATCC, JIS and ISO standard microbial methodologies. They also provide consulting in antimicrobial testing protocol design for those clients that required customized testing.
