Precision Metering System
Manufacturer: Parker Hannifin
The ChemTecTM provides programmable feed scheduling for chemical reactors, bioreactors and fermenters either by weight or volume. Both linear and exponential feed strategies can be readily implemented. When interfaced with an electronic balance, the ChemTecTM can also be used to maintain vessel or reactor weight in diafiltration or perfusion applications, it can also act as a pH controller for pH maintenance or simple end point titration. The ChemTecTM can regulate feed or trigger alarms based on external sensors such as SciPres®, SciTemp®, as well as 3rd party analogue outputs such as turbidity sensors. It can also be interfaced with a 6 port rotary valve for automated solution handling
