PH CONTROL AND CONTAMINATION ALARM SYSTEM OF BIOREACTORS FOR PLANT TISSUE CULTURE

摘要

PURPOSE: A pH control and contamination alarm system of bioreactors for plant tissue culture is provided, thereby simultaneously controlling pH of several bioreactors and detecting contamination thereof at an early stage. Therefore, high quality products can be produced. CONSTITUTION: A pH control and contamination alarm system of bioreactors for plant tissue culture comprises a plurality of bioreactors(1,2,3); pH electrodes(4,5,6) installed within the bioreactors(1,2,3) and detecting pH of the medium in each bioreactor; an integrated controller(7) receiving pH values and processing them; a computer(13) connecting the integrated controller(7) and providing the processed data results; and a plurality of pumps(10,11,12) which introduce one solution selected from NaOH solution(9) and HCl solution(8) into the bioreactors(1,2,3) according to the pH measuring modules by the integrated controller.
