BactoScan™ FC

An uncompromising approach to milk analysis

Based on proven FOSS technology, BactoScan™ measures the hygienic quality of milk by analysing bacteria in raw milk. Delivering results in just minutes, BactoScan allows farmers or milk testing laboratories to take action fast to preserve and enhance milk quality.

BactoScan FC Semi

BactoScan FC semi

The BactoScan FC semiautomatic employs the proven BactoScan analysis method but is scaled down to fit laboratories with limited sample throughput by removing the sample conveyer

CasesBacteria in milk – then and now

A sample of raw milk looks exactly the same as 30 or 40 years ago. However, there are far fewer bacteria in milk samples taken today.

BactoScan™ FC is based on flowcytometry technology that enables precise and instant milk bacteria analysis. Flowcytometry is a technique that counts and characterises 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
1. 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
2. During the incubation period, the bacteria are stained with a DNA-specific staining medium
3. 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
4. A very precise syringe is used to pass the whole sample through a flow cell, presenting the bacteria one by one
5. The electronics count the pulses and display them in a pulse height analysis diagram on the PC monitor.

Bacteria

Superior accuracy through individual bacteria count

Because the BactoScan FC counts all bacteria as single cells and not clusters it gives a uniform high performance with accuracy, repeatability and reproducibility of results. Unlike methods such as the plate counting method, BactoScan FC cannot be influenced by the operator and it can analyse raw milk samples directly without prior heating or dilution, which can affect precision.

Accuracy: Typical Sy,x < 0.25 log units in the entire measuring range.

Reference method: Standard Plate Count (IDFStandard 100B: 1991).

Based on proven FOSS technology, BactoScan™ measures the hygienic quality of milk by analysing bacteria in raw milk. Delivering results in just minutes, BactoScan allows farmers or milk testing laboratories to take action fast to preserve and enhance milk quality.

High performance capacity

BactoScan™ FC can analyse up to 150 milk samples per hour with upgrades available to meet the requirements of all milk testing laboratories. This high performance capacity enables a high throughput of daily samples and frees up testing staff for other purposes.

Models

50L, 50H: 50 samples per hour

100L, 100H: 100 samples per hour

150L, 150H: 150 samples per hour

Integrated milk testing system

BactoScan™ FC uses the same efficient conveyor system as other FOSS instruments such as Fossomatic™, CombiFoss™ FT+ and MilkoScan™ FT+. For laboratory personnel this means they only have to learn how to use one user interface and can enjoy the benefits of easy integration of data.

Integrated software platform

BactoScan™ FC, Fossomatic™, MilkoScan™ FT+ and CombiFoss™ FT+ all share the same powerful Foss Integrator software platform offering advanced data handling and storage facilities for traceability while a common user interface promotes more efficient laboratory operations.
