Mass flow controller

Precise gas control for fermentation

Buerkert (Germany) has introduced a mass flow controller compliant with USP Class VI. The product provides CANopen connectivity.

The challenge when producing bacteria, fungi, or cell cultures lies in the exact adherence to the respective general requirements. Above all, the precise regulation of gas quantities in fermentation processes must be adapted to the needs of the constantly increasing cultures. Buerkert Fluid Control Systems has developed mass flow controllers (MFCs) featuring a wide adjustment range, repeat accuracy, and documentation functions for reproducible processes. The devices comply with the approvals USP Class VI, FDA, 3.1 certificate and EC 1935.

The MFCs can calibrate four different gases. With just one device, the user is able to control the common fermenter gases such as air, oxygen, nitrogen, or carbon dioxide according to the needs of the respective cultures. The Type 8741 and Type 8745 cover flow ranges for nitrogen from 0,010 to 160 l/min and from 20 to 2500 l/min. The wetted parts are made of stainless steel to prevent ferment contamination.

Due to direct measuring sensors, the MFCs with high repeat accuracy are also suitable for the smallest gas quantities. In combination with the integrated, direct-acting proportional valve, they enable a dynamic control. Process data such as gas pressure and gas flow rate can be transmitted variably in conjunction with the Buerkert EDIP (Efficient Device Integration Platform).

The deeply embedded CANopen network is also accessible for the user of the mass flow controller. Gateway devices to other network technologies are available from the supplier. Of course, CAN host controllers can be connected directly to the CANopen network.
