Cultivation of bacteria at constant cell concentration
Biotronix

Biotronix_EloCheck
Application

When cultivating bacteria in culture vessels, the growth of bacteria is usually reduced after some time. The depletion of nutrients and the enrichment of toxic substances usually enable cultivation only over a short time. A bacterial culture can be cultivated indefinitely at constant quality by adding exact volumes of fresh nutrients and permanent harvesting of excessive culture volume..

 

The company biotronix uses its own online photometer EloCheck for controlling our REGLO Analog pump. Since sterile medium is pumped, all tubing and feed lines must be sterilized at 121°C before the cultivating process is started.

(For the use of the analog output and the schematic diagram of all fluidics, refer to:
