Stirred-tank bioreactor / fermentor GJA series

for the pharmaceutical industryfloor-standingglass

Load Proportion 65-80% of total volume, 70% optimum Vessel Material glass body and stainless steel lid and bottom The high ratio: 2:1 Mixing method: Mechanical drive Sterilization method: In situ sterilization Control system: Siemens PLC, industrial LCD touch computer control, parameters can be set to store, can be remotely connected to the computer through the USB interface, the data Stirring system high-powered stirring oar, antifoam oar; AC electrical machine: infinite speed variation; rpm in the fermenter: 70~1200rpm±1%,The height of the stirring oar can be adjusted, too. Temperature detection and control Heat by thermostatic water tank and circulate by circulating pump(Grundfos, Denmark), autocontrol (cooling) water+5°C)~65°C±0.1°C, temperature probe(US) pH detection and control 2.00-12.00±0.05pH, autocontrol by adding acid and base, pH sensor (Mettler, Switzerland) and shielding lead (Mettler, Switzerland). fermenter is autocontrolled with peristaltic pump DO detection and control 0-150±3% displaying precision 0.1%, sensor (Mettler, Switzerland) and shielding lead (Mettler, Switzerland) Feed control fermenter uses peristaltic pump (Longer) to add meterials Antifoam control Tested by sencor and added antifoamer by peristaltic pump Intake control (air) :manual control rotameter pressure detection and control Pressure Control: Pressure meter and digital display and digital remote control, pressure control
