For controlled growth in shake flasks and fermenters BCpreFerm - the whole gas analysis for the scale-up process BCpreFerm by BlueSens is a complete analyzing system made for the analysis of metabolic processes. It is consisting of up to 6 CO2- and O2-senors, a BACCom data multiplexer and the FERMVis-software for automatic data recording. By the modular structure of the system, BCpreFerm can be connected to shake flasks as well as to fermenters. BCpreFerm can also be added easily to existing bioreactors. In contradiction to central gas analyzers, the use of additional gas coolers, complicated lines, pumps and valves and the complicated processing of gases is no longer necessary. The CO2 and O2 sensors determine the respective gas concentrations continuously and directly in the fermenter or via a flow adapter. Running continuous measurements of the CO2 and O2 contents in shake flasks and fermenters facilitates controlled trial conditions with simultaneous analysis of the metabolic processes. Oxygen or substrate limitations can be detected along with metabolic transpositions. Furthermore, a time specific analysis of the desired product is made possible. For improved comparability, the measurement system BCpreFerm can be used for shake flasks and fermenters. BCpreFerm consists of: up to 6 CO2- sensors up to 6 O2- sensors Multiplexer BACCom and BACCom EB for connecting 12 sensors through one interface (RS232, USB, Ethernet) FermVis data acquisition software, calculation of the OTR, CTR, RQ Applications: Cultivations in: Shake flasks Fermenters Controlled growth through: parallel analysis of CO2 and O2 display of OTR, CTR and RQ defined trial conditions Your advantages: additional information about the metabolic processes during cultivation high level of comparability adjustable limitation the modular construction of BCPreFerm
