Bioreactor vessel description:
- total / working volume: 15/10 l; 30/20 l; 42/30 l
- a stainless steel jacket that allows you to maintain the set temperature even when working with small volumes (the minimum working volume of the fermenter is 3.0 liters)
- there are stainless steel bumpers inside the vessel
- stirring speed - 10-1500 rpm
- top mechanical drive
- 6-blade Rushton stirrer
- temperature range - 5 to 70 ° C above ambient temperature
- maintaining the temperature - electric heating or steam generator
- cooled with tap water through a heat exchanger
- membrane filters for gases at the inlet and outlet of the system
- control of the gas flow rate using a rotameter, a thermal valve with flow level measurement and a gas mixing module
- using the Infors GasMix system to control the pO2 level at a constant gas supply or to account for microaerophilic quantities, which allows mixing gases based on the value of the level of dissolved oxygen in the culture medium
- accurate calculation of the proportions of the composition of gases
- reflection on the color touch screen of the preselected flow rate and the planned dose of oxygen in the mixture
- possibility of additional equipping with rotameters, level controllers, solenoid valves of outputs for O2, N2, CO2

Iris software allows you to:
- display fermentation parameters and display them in the form of a graph in one window
- write data to computer memory
- transfer recorded data to other programs
- set alarms for critical parameter values
- perform programming of the sequence of changing parameters during fermentation
- Network up to four Labfors 4 fermenters using the networked version of Iris software
