Sampling

Sampling is the fundamental step of sanitary water testing. An appropriate, representative sample is critical for accurate results. MilliporeSigma offers products for collecting samples from both in-line purified water and water in the field.

Filtration

Filtration is a key step for maximizing recovery of microorganisms while avoiding exogenous contamination. MilliporeSigma’s filter devices are pre-sterilized and ready-to-use, eliminating time-consuming preparation steps. Additionally, all the filtration devices are designed with features that prevent exogenous contamination and facilitate uniform recovery of microorganisms. Hardware and accessories for filtration, such as membrane dispensers and pumps, as well as validation protocols, validation support, and maintenance contracts combine to provide a complete solution for all your filtration needs.

Culturing

Culturing is an important step that is affected by the quality of the growth medium. As the first supplier of pharmaceutical materials worldwide, MilliporeSigma offers you a wide selection of culture media. We carefully select and analyze the individual ingredients of culture media to ensure that final culture media products provide consistent performances. From 2 ml liquid media in ampoule to dehydrated culture media to ready-to-use media, we can respond to our user’s needs and to regulations requirements.

Incubation

Incubation is the final step before enumerating microorganisms. MilliporeSigma offers single and dual chamber incubators to provide dependable performance in both the lab and the field. These incubators are designed for recovery of indicator organisms (total and fecal coliforms, and fecal streptococci) as well as other microorganisms.
