Rapid enumeration of individual bacteria in raw milk.

The IBC series uses flow cytometry for the rapid enumeration of total bacteria in milk. They are the ideal solution for any processing plant or test laboratory involved in quality assessment of milk.

Two IBC models are available, making it easy to select an instrument that fits the needs of your workflow.

BactoCount IBCm

The BactoCount IBCm is a semi-automated instrument that uses flow cytometry for the rapid enumeration of individual bacteria and somatic cells in milk. The rapid test for bacteria makes it an ideal solution for any processing plant or test laboratory involved in quality assessment on milk.

The IBCm is a general flow cytometer and its applications have been expanded to include the counting of somatic cells in raw milk. This gives a laboratory a convenient 2-for-1 solution when making laboratory investments.

  • Analyzing time for bacterial count is less than one minute and sample preparation is completed in less than 10 minutes
  • Analyzing time for somatic cell count is less than one minute, no sample preparation needed
  • Use of a standard computer offers flexible data output options
  • Easy operator-assisted sample preparation
  • Low-maintenance design

Recognized by both NCIMS and MicroVal organizations. The BactoCount IBCm is based on the BactoCount IBC 50-150 models which have been approved as an alternative method to the IDF 100B:1991 reference method for the rapid and accurate determination of the hygienic quality of cow, sheep and buffalo raw milk for payment purposes. The IBCm meets AOAC 986.33. Validated by MicroVal to be at least equivalent to the EN-ISO 4833-1:2013 and 4833-2:2013 reference methods for the enumeration of microorganisms in raw cow milk (Certificate n° 2013LR44)

The practical application varies slightly depending on whether it is somatic or bacterial cells that are counted but the general principle is the same: the cells are stained with a fluorescent dye that inserts into the intracellular DNA followed by detection and enumeration by a flow cytometry based cell counter.

BactoCount IBC

The BactoCount IBC is a fully automated instrument that uses flow cytometry for the rapid enumeration of individual bacteria in raw milk. The high speed of this model makes it the ideal solution for mid to large size laboratories that need an easy to maintain, exceptionally fast bacteria counting system.

  • Analyzing up to 150 samples per hour, (BactoCount IBC 50, BactoCount IBC 100, and BactoCount IBC 150)
  • Fully automated system provides a steady flow of samples
  • Low maintenance, reliable performance
  • Validated to be at least equivalent to the EN-ISO 4833-1:2013 and 4833-2:2013 reference methods for the enumeration of microorganisms in raw cow milk (Certificate n° 2013LR44)

The IBC can be used as an alternative method to the IDF 100B:1991 and AOAC 986.33 reference methods for the rapid and accurate determination of the hygienic quality of cow, sheep, and buffalo raw milk for payment purposes.
