Foss – BacSomatic™
BacSomaticTM provides rapid hygiene testing of milk. BacSomatic is the first-ever integrated bacteria and somatic cell tester and offers full automation for minimal reagent handling and consistent test results.
Integrated bacteria and somatic cell tester
Automatic and fast alternative to manual assay, providing instant, simultaneous results for individual bacteria and somatic cell count within 9.5 minutes and 1.5 minutes for somatic cell count alone.
More accurate than alternative methods
A fully automated procedure avoids the risk of human error and inconsistency, while ready-to-use reagents in an enclosed bag system, ensure the exact same dosage for every measurement. A sensor in the reagent bag indicates the number of available tests remaining. The unique reagent concept includes control samples for quality assurance and GLP. Online remote monitoring ensures consistent performance and high uptime.
Simple and flexible to use
Built on a long heritage of Foss analytical technology and backed by global Foss support, BacSomatic combines robust performance with a modern interface. Very easyto-use with intuitive touch-screen operation for smarter money-saving decisions on how to use milk.
Sample types
Raw cow’s milk and buffalo milk
Parameters
Individual Bacteria Count (IBC) Somatic Cell Count (SCC)
Technology
Flow cytometry technology, counting individual bacteria cells and somatic cells. The IBC results can be converted to CFU results. BacSomatic software includes an easy and rapid tool to develop a robust conversion table between IBC and CFU.

Highlights
Rapid results for somatic cell count and bacteria count
Results for bacteria count and somatic cell are delivered within nine and a half minutes (1.5 minutes for somatic cell alone). The method is the same as the well-known methods used in FOSS BactoScan™ and Fossomatic™ analysers used by raw milk testing centres around the world.
Flow system
Unique flow system directs the sample to a bacteria incubator or somatic cell mixing chamber where the cells are stained and then measured by the laser source. Two different laser intensity levels are used according to whether a somatic cell count or bacteria count is to be performed.
Automated reagent dosage and handling
Automated procedure ensures exact reagent dosage every time and avoids the need for reagent mixing. The reagent bag system is specifically designed for safe, contact-free use of reagents. The reagents are provided ready-to-use in bags. Place the bags in the instrument and close the door and you are ready to test.
