BIOTRON GMII 2ch, 4ch, 6ch

Multiple Lab fermentor capable of ORP monitoring, plural controllers and large volume up to 84L (total volume) with space saving design and user basis controller program



BIOTRON GMII is for multiple culturing experiment and able to compare the results simultaneously.
This model is recommended to use in laboratory, industrial R&D center, bioprocess institutes and biomass company.
Biotron GMII consists of Biotron GXII controllers in 2channel/4channel/6channel, and is made into slimmer shape to be convinient for user through plate work.



-Intelligent self diagnostic system to maintain fermentation process from start to the end : Diagnostic, Setup, Dead Band, Offset, Warning, Feeding condition

-Programmable multi stage operation : Setting pH, DO, Foam, temperature for each stage to the end of the fermentation process

-Qualified for dense fermentation : DO-stat, pH-stat, Exponential feeding,etc

-Easy to setup feeding program

-Parallel design of vessel and controller : 4 peristaltic pump and pH, DO, foam, temperature sensor port

-Remote control available in PC with data logging system

-Self data logging system within fermentation controller
