The practical new type bioreactor shaker has the function to measure, set, and control real time pH value, the feed speed according the requirements. It may obtain the data relating to pH value change during the fermentation. It provides scientific data for high volume bacteria selection, seed propagation, ingredients of fermentation process, lower labor intensity, represents the data succession and trend, and shorten the time of production development. It is applicable for different phase of product R&D, production in chemical engineeringThe bioreactor-type shaker discard the disadvantages of traditional ones and have the following unique functionsOnce-forming glass triangle bottle with multi pH electrode and feed socket may simultaneously measure pH value during the fermentation, ensuring the stability of the culture environment and pure cultureStainless steel angle baffle greatly improves the oxygen supply environment in the culture baseThe atom continuous feed control system satisfy your requirements for culture base t different bacteria growth, and has no change to the environment for microorganism, and ensures the continuation and stability of the cultivationWith pH value curve that changes with time obtained by the device, feed control (feedback controlled with pH control series or non-related control), and elements of the culture base, the device can get the metabolism of the germs and provide the evidence for technical research after bacteria selection and further optimizing the fermentationTouch screen pH display and control meter sensor system facilitates setting and marking pH valu
