Optional modules can be ordered · For temperatures below room temperature (Cooling System) · pH control (pH Control System) · control Dissolved Oxygen (DOdisplay and control system) · Foam Control · Feed & Harvest ·
Datalogging Software ·
Starter Kit · Extended Warranty Packs. (Order these with the basic unit of yourchoice)
For attaining temperatures below room temperature. 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.
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. It uses two peristaltic pumps with acid & base reservoirs which automatically add acid or base depending on the pH set and actual values.
Dissolved Oxygen Display & Control system:
With two gases sparging system. This module consists of a low-maintenance autoclavable glass DO electrode to measure and automatically sparge air to control the dissolved oxygen levels of the reaction.
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.
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.
Data Logging Software:
MS Windows based software that displays graphs of and logs pH, temperature, DO
and RPM values to MS Excel sheets.
