The SFR vario offers online monitoring of oxygen, biomass and pH or CO2 - simultaneously. Online measured biomass data can be correlated with parameters like optical density, cell dry weight, or cell concentration.
This way it is possible to get real-time information on e. g. OD600 development. The device optics can read out one oxygen and one pH or CO2 (CO2 Technical Data) sensor spots - integrated in the ready-to-use cultivation vessels - and also comprise a dedicated optical set-up for biomass monitoring. The oxygen uptake rate (OUR) can be calculated from the slope of the online oxygen measurements. The system has two long-lasting, rechargeable batteries, and is compatible with any standard shaking incubators. Up to 4 SFR vario can be controlled from the SFR vario software. Measurement data are transferred wirelessly via Bluetooth to a PC / notebook.

- Getting Started
This device comprises rechargeable batteries (accumulators) for self-contained
power supply. Rechargeable batteries may be replaced by the manufacturer only.
Rechargeable batteries are subject to normal wear which is more or less
pronounced depending on operating and storage conditions. This normal wear is
no defect which is covered by the device warranty.
