BactoScan™ FC is based on flowcytometry technology that enables precise and instant milk bacteria analysis. Flowcytometry is a technique that counts and characterizes particles and cells.
The principle behind flowcytometry is quite simple: A suspension of cells is stained and forced through a capillary tube, which is illuminated in front of a microscope objective. Every passing cell is then registered by photo electronics attached to the microscope.
The BactoScan™ FC counts the bacteria;
● By incubating the milk with a unique incubation liquid and by employing mechanical treatment,
all components in the milk are broken down except for the bacteria. The bacteria clusters are also
separated into single bacteria.
● During the incubation period, the bacteria are stained with a DNA-specific staining medium.
● At the measuring point, the sample material is exposed to a light beam from a laser source, forcing
the stained bacteria to emit red light - one light pulse for every bacteria passing the beam.
● A very precise syringe is used to pass the whole sample through a flow cell, presenting the bacteria
one by one.
● The electronics count the pulses and display them in a pulse height analysis diagram on the PC
monitor.
