The 3M microbial luminescene system (MLS), available from 3M Microbiology , is a rapid microbial detection system using ATP Bioluminescence in a microwell based instrument to detect the presence of microbial ATP in sterile dairy and dairy-type products.
The 3M microbial luminescence system allows rapid assessment of Ultra Heat Treated (UHT) or Extended Shelf Life (ESL) milk and sterile dairy samples that have already been incubated within their pack. This is a rapid alternative to traditional microbiological assessment of these samples.
The 3M MLS system is specially designed to exclude the ATP from non-microbial sources and measure only microbial ATP in a light output format of RLUs (Relative Light Units). The measurement of microbial ATP represents the presence of microbial contamination in the product.
