Desktop fermenter, compact structure,easy to operate

Ventilation System

l Deep ventilation, equipped with stainless steel annular distributor. l Glass rotameter display, pressure gauge display, manual valve to adjust the flow. l Equipped with American Sartorius high-efficiency sterilizing filter, the filtration accuracy is 0.2μm, and external compressed air is required. l Equipped with high-quality decompression device, continuous and stable gas supply. l The optio

Temperature Control

On-line detection, digital setting, automatic/manual control; German Pt-100 temperature probe, built-in electric heating device and external cooling water for automatic temperature control.

pH Control

On-line detection, 1-way or 2-way peristaltic pumps automatically feed alkali or acid for adjustment; imported Swiss Mettler/Hamilton pH electrode, which can be sterilized by high temperature steam.

Dissolved Oxygen (DO)

l Online detection, the range is 0-100% or 0-200%. l Imported Swiss Mettler/Hamilton DO electrode, which can be sterilized by high temperature steam. l Can be linked with speed control, can be linked with feeding control.

Feeding Control

Standard 1-way peristaltic pump time proportional feeding,cumulative display and recording of feeding volume;10-segment feeding program, can be linked with DO.

Defoaming Method

l Conductive foam electrode, automatic alarm for abnormal foam conditions; l Standard 1-way peristaltic pump automatically/manually feeds defoamer, cumulative display and record of the amount added; l The defoaming pump can be switched to a feeding pump and used as a feeding pump, and 10-segment feeding programs can be set.

Control System

Industrial-grade control system, using Siemens PLC controller, 64-bit true color touch screen operation interface, complete functions and stable operation.

Sterilization Method

Off-site or on-site sterilization
