Brief introduction: High efficiency magnetic stirring system without mechanical seal, sealing performance is better, especially for a long time of continuous cultivation, cleaning more convenient; built-in or external white cold fluorescent lamp lighting system (light source intensity adjustable); It is suitable for the study of cell light and culture of transitional experimental plants from laboratory scale to large production. Indicators and configurations: Tank system: imported SUS316L high quality stainless steel, no dead angle in tank; using large angle of view tank liquid level observation mirror 12V safety lamp to resist acid and alkali corrosion, inside and outside surface treatment: internal and external polishing mirror surface treatment, polishing precision Ra0.8; to reduce the chance of contamination, And easy to clean; diameter to height of 1: 2, sterilization can be stirred at the same time, can thoroughly sterilize the medium. Mixing system: high magnetic stirring system with upper suspension (strongly recommended), no mechanical seal leakage, bottom no thimble tank bottom magnetic stirring, Germany imported SEW motor (or high quality DC motor) and imported governor to ensure stable speed; High performance agitator, defoaming propeller, AC speed regulating motor, stepless speed regulation. All the inner parts of the tank are installed on the cover of the tank, which is easy to maintain and clean. The standard six-blade propeller for fermentation is adjustable in height, and the different types of agitator can also be replaced according to the special requirements of the fermentation process. The magnetic stirring system adopts special permanent magnetic material, special processing technology, never fade magnetism, stirring speed is not lower than the technical requirement in the lifetime of fermentor, and can also be achieved in high viscosity medium. It can also be directly coupled with mechanical agitation, with a tank top mechanical seal system, British mechanical seal (John Crane), high performance agitator, defoaming propeller, AC speed regulating motor, stepless speed regulation, High-power speed-changing mechanism makes stirring stable and running freely without adding lubricating oil. Automatic set control range 50 rpm ~ rated speed ±1. Temperature control: jacket water bath heating, automatic control, temperature control of cooling water temperature + 5 ℃ ~ 65 ℃ plus or minus 0.2 ℃ Foam control: automatic PID control and alarm, peristaltic pump add defoaming agent automatically Feeding control: PID automatic setting peristaltic pump switch control, automatic flow addition and measurement. PH control: adopt Swiss original mettler electrode (compatible with high quality domestic electrode), peristaltic pump automatically add acid and alkali, accurately control pH, display range: 0.00~14.00 + 0.01, automatic control range: 2.00~12.00 + 0.05. DO control: adopt Swiss original imported mettler electrode (compatible with high quality domestic electrode), and control the speed (air flow, feeding and other optional), 0-150 + / -3%, showing the accuracy 0.1%. Pressure control: manual control, instrument display Air flow: manual control, instrument display Control system: single can be controlled by BIOTECH-2002 biological process controller and monitoring software of BIOTECH-FCS fermentation. If multiple or multistage fermentation tanks are used, more measurement and control functions can be realized by using a BIOTECH-3000 biological process controller.
