GMI is proud to carry brand new laboratory scale fermenter alternatives to New Brunswick Sartorius B. Braun and Applikon. The modular Major Science F1 Lab Scale Fermenter is a programmable fermentation system with an 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 Major Science F1 Lab Scale Fermenter is an excellent benchtop laboratory scale fermenter with full warranty and support from GMI with superior economics and price point

Bench Top Fermenter Componentry:

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 0~10 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.
