Stirred-tank bioreactor / fermentor

laboratoryfloor-standingstainless steel

Working volume: 4.5-8 liters Material: 316L stainless steel with material contact to the other 304 stainless steel Control system: Siemens PLC, industrial LCD touch computer control, parameters can be set to store, can be remotely connected to the computerthrough the USB interface, the data Working volume 4.5 to 8 liters and The main material of the fermenter is made by 316Lstainless steel. The design pressure: P(inside)= 0.3Mpa, P(interlayer)= 0.3Mpa, The polishing precision: Ra0.4 ~ 0.6, the ratio between diameter and height: 1:2.3 Sterilization method : auto sterilizing in situ Stirring system Mechanical sealing system at the top of the fermenter; high-powered stirring oar, antifoam oar; AC electrical machine: infinite speed variation; rpm in the fermenter: 70~1000rpm‡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 2.00-12.000.05pH, 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 0-15013% 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
