Lab Scale Fermentor

Features Lab-Ferment or is controlled by its own precise controller, is able to communicate with computer through Online monitoring, and to continue cultivation for a long time with its strong stirring skill. Cylindrical structure for optimum cultivation Easy to use and to maintain Completely sealed from outside pollutants Product material is free from pollution, corrosion, or abrasion. It has little physical or chemical change under high temperature and high pressure. We adapted highly reliable controllers to control temperature, pH, Do, pressure, and stirring speed, which allow you to measure at a stable and exact condition. The vessel temperature is measured by RTD(PT100 âÂ?¦) sensor, and is controlled by PID. Gas for cultivation is supplied on an aseptic condition. (Air, O2, CO2, N2 and etc. may be used depending on the character of the cells,.) A baffle is installed to prevent the vortex due to stirring and to increase an efficient stirring. Acid and alkali bottles are equipped to control pH.
