The gas mixing station allows the user to optimize cell growth conditions by independently supplying up to four gasses to the fermentation process. Parameters such as dissolved oxygen and pH can be controlled by adjusting the gas composition supplied to the system. Four manually adjusted flowmeters control the flow rate of each gas, while the 4 solenoid valves automatically open or close in response to the culture conditions. The Gas Mixing Station can be operated in either manual or automatic modes.
Maintain optimal control over culture DO level by installing this optional mass flow controller. The mass flow controller can accurately adjust the flow rate of incoming oxygen and is resistant to fluctuations in gas pressure, ensuring precise control and repeatibility of experimental conditions
The CO2 / O2 off-gas analyzer provides real-time measurement of carbon dioxide and oxygen concentration of the bioreactor exhaust gas. The CO2 concentration is determined using a self-calibrating non-dispersion infrared sensor, while an electrochemical sensor monitors the oxygen concentration. Using this information, the user can continuously monitor metabolism and analyze cell growth parameters.
Our special implemented online cell density device allows you to obtain direct information about your cell growth rate and cell density; as these values are critical to many bacterial, yeast and animal cell cultures. Online cell density device combines monitoring and probing system, also performs accuracy precisely. Having trouble determining the cell growth rate? Our online cell density is the key to your solution.
The ORP probe measures the oxidation-reduction potential of the fermentation media, which is a crucial indicator of anaerobic conditions/reactions. This low-maintenance and sterilizable probe is designed to withstand repeated experiments.
Electropolish of the vessel tank is offered as a higher sanitary grade surface finish. EP surface finish is an addition to the standard mechanical polish (MP) which provides a smoother surface area to minimize residual residue.
* Note that this option MUST be requested at your initial inquiry, later-on additions after completion of construction is not possible
Transfer piping of your resulting product/medium between vessels is offered for the convenience of operation.
Automated transfer using pressure in addition to directional control with valve regulations offers fast and easy operation.
The turbidity probe measures the turbidity level of the fermentation media, which provides you an indication for the metabolic reaction and in terms allows you to maintain a steady cell level.
The load cell provides weighing capability to your fermentation process. Weighing the substrate feeding can indicate how much substrate was added during the fermentation process, which allows the user to provide more accurate control accordingly to what the process needs.
An operation platform is offered to provide optimal operation convenience. Stainless steel constructed platform offers elevated height for full observation of the headplate when standing on the platform, the chest-leveled positioning of the vessel headplate prevents falling into the vessel.
