MILLIPLEX® portfolio of immunoassays from Merck is the largest portfolio of multiplex biomarker assays, based on Luminex® xMAP® technology, offering you high-quality results, so that you can do your best work while saving time, labor and cost.

Merck’s Membrane filtration technique complies with international standard such as standard methods for Examination of Water and Waste water, US EPA, and EU testing procedures for drinking water or other filtration testing it’s simple: the test sample is filtered through a microporous membrane, allowing the retention of microbial contamination on top of the membrane. Rinsing removes residues that might inhibit the growth of microorganisms. Once the sample is filtered, nutrient medium is added to promote growth of microorganisms for recovery. For testing non-filterable samples, Merck offers a large selection of culture media of the high quality.

Our Lab Water purification system portfolio offers a broad range of pure and ultrapure water purification systems and services designed for scientists working in pharmaceutical, clinical, academic, industrial, research, and government laboratories — in both validated and non-validated environments.
