FLM300 Fluorophos ALP Test System

The Fluorophos ALP assay is a rapid test for verifying proper pasteurization of dairy products. Alkaline Phosphatase (ALP), found naturally in raw milk, is destroyed at temperatures slightly above the temperature necessary to destroy microorganisms pathogenic to humans. Measurement of residual phosphatase after pasteurization offers a means of verifying the products are heated to the proper temperatures and are not contaminated with raw milk. The Fluorophos ALP assay measures the ALP activity in dairy products, allowing the user to monitor the completeness of pasteurization and detect raw milk contamination.



Test results automatically appear in approximately 3 minutes


Single sample test system


The most sensitive test for pasteurization on the market. Detects to 0.003% raw milk contamination.


Can be used to test pasteurization of cow, goat, sheep and other species of milk


The Fluorophos ALP Test is the ISO/IDF Reference method. (ISO11816-1:IDF 155-1 and ISO11816-2:IDF 155-2) It is also the standard for confirming proper pasteurization for the NCIMS/FDA, AOAC, IMS, and CEN.


The Fluorophos ALP Test detects ultra-low levels of raw milk contamination
