The Modular Baby fermentor is designed for total flexibility in utilization versatility and highly economical for use in all educational institutions and R&D laboratories.THE BASIC FERMENTOR consists of:
· Glass vessel assembly 1 litre or 2 litre capacity.
· Magnetically coupled bottom agitator.
· Aeration system comprising of built in air compressor, inlet & outlet filters, Rotameter and needle valve.
· Temperature control using digital PID controller and PT 100 sensor, heater and cooling water valve. SEPARATE INEXPENSIVE ADD- ON MODULES are available for control of all the parameters which allows operation of systems ranging from simple batch cultures to fully instrumented continuous culture system.
· pH control module this module monitors and controls pH within an accuracy of 0.1 pH by adding acid or alkali using two built in peristaltic pumps & Digital PID controller. Signal output can be sent to a recorder or data logging using computer. The autoclavable electrode is supplied with a special SS holder.
· Timed Pump module - This module is used to add small volumes of antifoam agent at regular intervals from 0-2 minutes or 2 ml/hr every hour using a built in peristaltic pump.
· Nutrient/ Harvest pump module - This module provides simultaneous control of nutrient addition and harvest removal from the fermentor using a dual head peristaltic pump with adjustable flow rates from 0.05 ml/min to 15 ml/min. Level can be controlled properly by choosing the speed and tubing size. Vessel volume between 200 ml to 800 ml can be maintained using the adjustable harvest tube depth.
· Oxygen control module - this module monitors and controls the dissolved oxygen content in the vessel by adding oxygen or nitrogen through automatically controlled solenoid valve. The digital PID controller controls oxygen within 5% of the set value. Signal output can be connected to a recorder or used for data logging in a computer. The autoclavable electrode is supplied with cable and fittings.
· Rack module - This module consists of a SS rack which can accommodate 5 litre capacity storage bottles and 250 ml sample bottles in addition to the fixing arrangement for the culture vessel during autoclaving. Totally loaded rack can be autoclaved in a 450 mm dia electrical autoclave. This saves space and facilitates easy handling.
