OmniFerm® Mini Parallel Fermenter Systems

The modular construction and the numerous customised diversity of variants provide a maximum degree of flexibility in comparison with standard systems.

The basic unit consists of a glass vessel with a stainless steel ­cover with all the required connections and an exhaust air cooler. Containers with working volumes from 150 to 1,600 ml are available.

The pH value is measured via an invasive pH electrode and can be regulated by CO2 /base or acid/base.

Gas injection can be applied by the headspace, a sparger or by a gas injection ring.

A solid-state temperature control system without heat transfer medium is used for heating and cooling, i. e. the vessel is heated and cooled over the base plate.

Highly precise pump drives for analysing pump hoses with dosing rates of 1 μl/min up to 30 ml/min enable exact dosing in semicontinuous and continuous operation. Laboratory balances may be optionally integrated in order to achieve controlled gravimetric dosing.

The stirrer is powered by a speed-controlled, wear-free, brushless DC motor A mechanical seal ensures the required sterility. Propeller, Rushton or diagonal blade stirrers are used. A magnetic stirrer with PTFE stirring rods is available as an alternative or supplement for gravity-sensitive micro-organisms.


OmniFerm® mini fermenters are sterilised by autoclaving. After dis­connecting the plug and the stirrer drive and the removal of the hoses from the pump drives the vessels may be sterilised within the autoclave.

Advantages

  • Full research fermenter functions
  • High level of automation
  • Extensive sensor system possible
  • Temperature control without heat transfer medium

Gas Mixing Systems

Graduated solutions are available for gas mixing. For most applications the triple multiplexed gas mixture OMNIFERM-GASMF with a common mass flow controller for all gases except for CO2 is sufficient. The compact module is fitted directly onto the rear panel of the fermenter control unit.

Variable area flowmeters with a manually activated needle valve can be fitted for simple applications.

A design with a separate CO2 mass flow controller is available for cell culture equipment. For sophisticated demands the OmniFerm® mini can be fitted with a mass flow controller for each gas separately.

A system comprising two 2-litre fermentation units which are connected to an OS. Additionally, it is intended that a stainless steel gas injection ring should be used in place of the standard silicone ring. Gas injection should be able to be regulated with the aid of a mass flow controller as a variation from the standard rotameter. The system is intended, for example, to be used for training and therefore the software bundle as runtime is sufficient.
