Fast & Easy Systems to Detect Microbial Contamination

Request Information

Rapid microbiological detection solutions from Merck for bioburden testing effectively address the diverse contamination issues which face the pharmaceutical, cosmetics, food, beverages and municipal/environmental water industries every day. Innovative rapid technologies provide several advantages over classical culture-based methods: earlier results, increased assay sensitivity, ease-of-use, excellent accuracy and reliability. Consequently, rapid technologies are gaining acceptance across industries. Although traditional methods are proven, they are also time and resource intensive, adding significant time-to-result (and thus delaying product release) because they require visual detection of Colony Forming Units (CFUs).

Merck’s Milliflex® Quantum, Milliflex® Rapid and EZ-Fluo™ Rapid Detection System, all rapid microbial detection solutions for water microbiology and bioburden testing, provide results three to four times faster than traditional methods, allowing corrective action sooner in case of contamination.

Here is what one of our customers says about our rapid testing devices:
“Milliflex Quantum is a simple easy to use system that allows Thatchers to maximize the production potential through faster microbiological test results.”
Richard Johnson, QC Manager, Thatchers
