GMI is proud to carry brand new laboratory scale fermenter alternatives to New Brunswick Sartorius B. Braun and Applikon. The modular MS-F1 is a programmable fermentation system with a user friendly interface design. It is offered as a complete system including all the necessary accessories. It can equip with single culture vessel or double jacketed culture vessel for different microbiological material. Its high reproducibility was proven in many experiments. There are two modes manual mode and programmable mode. In addition Cascade and Acid-start condition are also built in the controller. It also has a one Controller- Two Vessel option available to save bench top space.

The MS-F1 is an excellent bench top laboratory scale fermenter with full warranty and support from GMI with superior economics and price point.

Bioegineering MS-F1 Laboratory Fermenter Components

A. Vessel: The electro-polished 316 stainless steel head and bottom plate fitted onto the single glass vessel.
10 ports with fitting for multiple application- such as pH- DO- Temp- Anti-foam- Sampling- Breeding etc.

B. Agitation: Top drive removable motor with real speed measurement. Single mechanical seal does not require spare parts or lubrication and performs excellently under pressure and under vacuum conditions. 3 ea of the electro-polished 316 stainless steel impeller.

C. Aeration: The unit is supplied with a flow meter (rotameter type 010 L/min) for the control of the flow rate of air into the bioreactor. L-type sparger : the geometry of the vessel combined with the right design of impellers provide the culture with optimal transfer rates and mixing.

Programmable Microprocessor Controller

A. 15 steps programmable temperature controller: PID controller with 15 programmable steps with
bottom heating plate combine with cooling valve and a temp range / accuracy : 0-90 C / +/- 0.1 C

B. 15 steps programmable agitation controller
PID controller with 15 programmable steps with a range of 0~1200 rpm

C. pH controller
1 combined actoclavable pH probe (in-gold type) with gelled electrolyte and accuracy range pH 2~12 / 0.01

D. DO display
Autoclavable ingold type DO probe and range of 0~100%

E. Antifoam controller

Stainless steel probe with electric insulation attached to a port on the head plate of bioreactor allowing height adjustment. Delay cyclical operation automatically controlled by two programmable timers.

F. Pumping versatility Four built-in programmable pumps can be assigned to more than five different functions via the keypad. These include addition of acid base chemical deformer and nutrients as well as the harvesting of culture. Control capability is also provided for an optional fifth pump. Adjustable flow rate for each easy load pump head and 15 programmable steps for each feeding application.
