Fermenter - sterilizer

• Stainless steel cylindrical tank with a diameter of 250 mm inside (200 mm), 340 mm high (300 mm), with double and triple jacket on the shell
• Minimum working capacity: 3 liters (or 1.5 L)
• Maximum working capacity: 10 liters (resp. 5 L)
• A Pt100 temperature sensor, mounted on a clamp
• A sample taking.

Bottom bottom : It is made of stainless steel and supports the stirring system. It is equipped with a drain valve. The bottom plate allows magnetic coupling between the motor and the shaker shaft.

Condenser : Condenser with stainless steel inner coil, removable.

Air injection circuit: It consists of a pressure reducer - regulator, a pressure gauge, a float gas flowmeter, an autoclave filter.

Lid: This is bolted to the ferrule and can be removed occasionally.

He understands :

• An air inlet with a dip tube and an annular diffuser delivering air bubbles directed towards the stirring turbine for good dispersion.
• A nozzle for the air outlet. This outlet is equipped with a sterilizable filter in place and a condenser
• A valve calibrated at 2.8 bar and an electronic pressure gauge
• An inoculation tube for injecting the culture medium
• A quilting allowing the introduction of acid and base
• A quilting for injecting the antifoam

Tank : it is equipped with 3 connections are provided for implantation of pH, oxygen or Red-Ox probes. and CO2 depending on the options chosen.

Additional equipment : 

- From 1 to 4 peristaltic pumps (depending on options), silicone fittings and tubing
- 1 filter for compressed air
- 1 condenser outlet filter
- 1 removable condenser (water circuit with turns)
- 1 gas flow meter with needle valve.

Electrical cabinet : Made of stainless steel, it includes the following elements :

• Regulator with timer for sterilization time management
• Two temperature controllers for temperature management during fermentation (cascade control)
• An oxygen transmitter / regulator (option)
• PH transmitter / regulator (option)
• Red-Ox transmitter / controller (option)
• Co2 transmitter / controller (option)
