Bioburden Testing for Municipal & Environmental Water
Reliable & Convenient Testing for Microbial Contamination |
Request Information |
Merck’s membrane filtration and culture media solutions for bioburden testing deliver fast and reliable results when sampling municipal or environmental water for microbiological contamination.
The Standard Test Method for Microbial Contamination
Merck’s membrane filtration technique complies with international standards such as Standard Methods for Examination of Water and Waste Water, US EPA, and EU testing procedures for drinking water. It’s easy-to-do: the test sample is filtered through a microporous membrane, allowing any microbial contamination to be retained on top of the membrane. Residues that might inhibit the growth of microorganisms are removed by rinsing. After the sample has been filtered, nutrient medium is added to promote the growth of contained microorganisms.
EZ-Product Family
The EZ product family is a range of Merck products for membrane filtration designed to perform microbiological analysis.

Ready-to-Use Culture Media
Merck provides a complete portfolio of ready-to-use (RTU) culture media for microbiological bioburden testing. Culture media based on Casein Soy Bean Digest or Sabouraud Dextrose are recommended for the microbial enumeration tests TAMC (total aerobic microbial count) and TYMC (total yeast/molds count). Specialized culture media are available for the detection of specified aerobic microorganisms.
