BactoScan™ FC is based on the flowcytometry technology. Flowcytometry is the key to precise and instant bacteria counting. Flowcytometry is a technique used for counting and characterisation of particles and cells. It can be directly translated as "the measurement of cells while they are flowing".
The principle 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 flowcell, presenting the bacteria one by one
The electronics count the pulses and display them in a pulse height analysis diagram on the PC monitor.
