3M™ Microbial Luminescence System MLSII

  • This is a specialised laboratory instrument (a luminometer with microplate format) alongside reagent kits, designed for rapid microbial detection in processed food and dairy products using ATP bioluminescence technology.
  • A microplate luminometer with five injector–dispensers used for rapid microbial detection.
  • Helps deliver results up to about two days faster than standard testing methods.
  • Shorter testing time means less stock needs to sit on hold and lets you respond to customers more quickly.
  • Faster product release also supports healthier cash flow.
  • Makes it easier to monitor and track quality performance over time.

Product Details:

  • A rapid microbial detection system using ATP bioluminescence in a microwell based System to detect the presence of microbial ATP in Ultra Heat Treated (UTH) and Extended Shelf Life (ESL) dairy and dairy end products.
  • 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.

How it works? 

  • The MLS II uses ATP bioluminescence to detect signs of microbial activity. ATP is found in all living cells, so when the system picks it up, it indicates possible contamination.
  • In practice, the sample such as a UHT or ESL dairy product is pre-incubated first. A small amount is then transferred into a microwell plate, where the MLS II reads the light signal produced and generates the result.
  • By removing or shortening the extra incubation steps required in traditional plate methods, the system produces results much faster, often saving two to three days.

Main benefits

  • Faster release of finished goods. Early detection of microbial issues cuts down the amount of time products need to stay on hold.
  • Lower inventory pressure. Getting results sooner means less stock sitting in storage, quicker turnaround and better cash flow.
  • Works across a wide range of products. It is particularly helpful for UHT and ESL dairy items, dairy alternatives and other heat-treated beverages.

Who would use it

  • Food and beverage producers, especially those handling UHT or ESL lines.
  • Quality labs that manage product release or routine microbial checks.
  • Any facility looking to speed up testing without compromising accuracy.
