Working volume: 8-15 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 computer through the USB interface, the data Working volume 8 to 15 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℃)~65℃±0.1℃，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 http://www.knikbioreactors.com/html/en/product/tubularcentrifuge tubular centrifuge for sale http://www.knikbioreactors.com/html/en/product/vavleandsupportsystem Valve and support system http://www.knikbioreactors.com/html/en/product/vavleandsupportsystem valve and support system for sale
