A temperature sensor and heater mounted in the reactor vessel and linked to a PID controller for accurate reaction temperature control. Sensor signals are routed to the I/O port for connection to a PC. A polarimeter device measuring optical transmission and angle of rotation. Protection devices for all electrical circuits. Three displays: PID temperature control (reactor temperature), a display for the angle of rotation, a display for optical transmission or temperature at polarimeter. The unit is used to demonstrate batch enzyme kinetics and enzyme characteristics. This is a reactor system specially designed to perform batch enzyme reaction utilizing the glucose isomerization reaction catalyzed by glucose isomerase. 

It consists of a bench-top unit onto which is mounted a reactor vessel in which the glucose isomerase-mediated reaction takes place. The reactor itself is made of clear acrylic, which gives good visibility. A cruciform geometry impeller constructed from stainless steel mesh retains the immobilized enzyme whilst allowing efficient mixing with the liquid reactant.
