Presentation BactoSense in Köniz

Presentation BactoSense at the water supply Köniz, raw water intake Selhofen-Zopfen near Belp / Bern

On Wednesday, 21st June, the new BactoSense method was presented directly at the raw water intake Selhofen-Zopfen near Belp / Bern. We were pleased to welcome 16 participants including end customers and guests from government agencies.

Our SIGRIST experts explained the technical functioning of the BactoSense and the experts of CHYN (Center for Hydrogeology and Geology, Neuchâtel) presented possible applications in ground water. CHYN, the water supplier Köniz and the company SIGRIST are currently testing a new method which is ready for practical application for continuous monitoring of the microbial quality of groundwater / drinking water based on flow cytometry.
With our new BactoSense method, the microbial state of water can be determined automatically. Its major advantage lies in the fact that the measuring results are available after only 30 minutes.

After the presentation, the participants could exchange experiences and make contacts while enjoying a refreshing Apéro.

BactoSense
This automatic flow cytometer has been specially developed according to the needs of the water industry for the microbiological monitoring of drinking water. BactoSense allows the determination of total microbial cell count (TCC) or intact cell count (ICC). With one BactoSense two measurements are possible thanks to different cartridges. The practical cartridge can be used for up to 1,000 measurements and is recyclable. Replacing the cartridge is as simple as replacing the ink cartridge on a printer. The entire program sequence – from sampling, adding reagent, mixing and incubation all the way through to measurement and cleaning – is carried out quickly and is fully automated. The measuring results are available after just 20 minutes. All manual processing steps can be omitted, removing the need for repetitive tasks and freeing up time for laboratory staff. The compact flow cytometer takes up little space and detects more than 99% of the bacterial cells. All operating materials (including waste material) are contained in a hermetically sealed, recyclable cartridge. This flow cytometer can be operated manually or automatically. An internal database allows all measured data to be reviewed and visualized across the entire measuring period. The results can be transmitted in analog or digital form, for example via mA, USB or web interface.
