pO2 control sterilisable Clark type oxygen sensor with fast response, automatic temperature correction, two-point semiautomatic calibration, dissolved oxygen (DO) control through regulation of the airflow rate
Range 0 to 25 mg oxygen/ l, in 0.1 mg/l steps
Air flow 0 to 5 l/min in 0.01 l/min steps, measured by precise mass flow meter, linearity +/- 3%, reproducibility +/- 0.5%
Control proportional valve controlled by microprocessor
For supplied air pressure 0.05 – 0.2 MPa (0.5 - 2 atm)
Agitation 50 W Vibromixer 0 to 20 Hz (0 to 1200 rpm) in 0.1 Hz steps (6 rpm) with 1 or more stirring discs; Sterility similar to magnetic coupling
Selectable parameter an additional parameter can be controlled by the instrument (foaming control, weight (for continuous cultures), pCO2, redox potential, conductivity, optical density, etc.); with standard 0-10V or 0-20mA output
Ports One large quadruple sampling or additions port with four needles with LAMBDA PEEK double-seal connections, used for sampling, inoculation, antifoam, feeds, harvest, addition of correction solutions etc., additional double ports are available.
Pumps up to 4 independent pumps (PRECIFLOW, MULTIFLOW, HIFLOW or MAXIFLOW) with speed variation from 0 to 100 % can be used with MINIFOR lab fermenter-bioreactor
Gas flow control In addition to pumps, several electronic flow controllers with flow rate ranges of 0-5 l/min (MASSFLOW 5000) or 0-500 ml/min (MASSFLOW 500) can be used for the controlled addition of gases (e.g. N2, O2, air, CO2) in cell cultures; freely configurable gas station module
