Diagnositic Mode


Diagnostic ModeUnique diagnostic mode in our lab autoclavable and in-situ sterilizable fermentors and bioreactors, enables the user to evaluate the health of the fermentor and its various components like pH and DO probes, peristaltic and diaphragm pumps, motors, sensors, calibration, reading etc. This allows remote diagnosis and support can be offered over the phone or email. This enables us to give better after-sales service remotely, often within a few hours of the user request.
The screen below shows the diagnostic mode of the agitation and stirring module of the fermentor. The motor speeds can be checked at Low, Medium and High speeds by pressing 1, 2, 3 keys. The motor RPM sensor tells the user if its working and consequently if the RPM is being calculated properly. At the company, the service person can ask the user to press and few keys and can remote diagnose the module without having to be physically present.Our fermentor and bioreactors are the only ones in India, to have this feature.

Standard Configurations available in Borosilicate Glass Vessels

Even our basic units mentioned below are fully functional fermentors and bioreactors. They have been designed in such a way that the units meet your budget yet at the same time are fully upgradeable in the future. So you can add advanced optional modules.

At the same time, the basic unit has systems to control motor speeds and agitation, motor RPM, temperature above ambient, will display pH values and has a 2-gas sparging and aeration system with filters and rotameters.

Basic unit has systems for Agitation Aeration Temperature control (from 3C above room temp. to 60C) pH display Fermentor diagnostics (for remote technical support).

Model BioFERMA-01-01Bioreactor basic unit with 1.5 litre working and 2.5 litre total volume.

Model BioFERMA-01-02Bioreactor basic unit with 3 litre working and 4 litre total volume.

Model BioFERMA-01-03Bioreactor basic unit with 5 litre working and 7 litre total volume.

Optional modules can be ordered For temperatures below room temperature (Cooling System) pH control (pH Control System) control Dissolved Oxygen (DO display and control system) Foam Control Feed & Harvest Datalogging Software.(Order these with the basic unit of your choice)

1-A. Cooling system:For attaining temperatures below room temperature: Control range (10C to 60C). In case you need to set temperatures below your normal room temperatures, order this module. For example, if you need to run fermentation at 20C and your room temperature is normally 30C, then order the cooling system.

1-B. pH Control system:The basic unit has an autoclavable gel filled glass pH electrode that displays the real time pH of the run. If you need to control the pH of the reaction, use this module. The control range is pH 2.0 to 12.0. It uses two peristaltic pumps with acid & base reservoirs which automatically add acid or base depending on the pH set and actual values.

1-C. Dissolved Oxygen Display & Control system:With two gases sparging system. This module consists of a low-maintenance autoclavable galvanic glass DO electrode to measure and automatically sparge air to control the dissolved oxygen levels of the reaction.

1-D. Feed/Harvest Module:With one bidirectional, variable speed peristaltic pump. Order this if you need to periodically add and remove media, inoculum and samples from the reactor vessel.

1-E. Foam Control Module:With one peristaltic pump and conductivity probe that monitors the foam. Anti-foam agent is automatically added to the vessel in case of excess foam.

1-G. Datalogging Software:MS Windows XP based software that displays graphs of and logs pH, temperature, DO and RPM values to MS Excel sheets.
