    Batch Enzyme Reactor

    Batch Enzyme Reactor

    A batch enzyme reaction system utilizing the industrially important glucose isomerization reaction
    (converting glucose to fructose) catalyzed by glucose isomerize. The purpose of the unit is to
    demonstrate batch enzyme kinetics and enzyme characteristics. The reaction takes place inside a
    stirred vessel where the stirrer itself is a porous basket inside which the enzyme is immobilized. A
    Polari meter device which is integral to the unit monitors the glucose and fructose concentrations with
    time.

    Boiling Process

    Boiling Process

    Sci-tech Evaporation Process Model TH 073 experimental unit can be used to examine and visualise the evaporation process in its various flow forms. This is done by heating evaporating liquid, Solkatherm, in a tube evaporator made of glass. Compared with water, this liquid has the advantage that its boiling point is at 36,7°C (1013hPa), whereby the entire evaporation process takes place at much lower temperatures and a lower heating power. The pressure can be varied via the cooling circuit. Negative pressure (vacuum) can be generated by a water jet pump in the cooling circuit.The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

    Catalytic Reactor

    Catalytic Reactor

    Sci-tech introduces students to the fundamentals of packed bed catalytic reactors. It is a bench-top unit available with either two or three reactor columns. Using two columns with a chemical catalyst allows a different particle size exchange resin to be used in order to study the effect of particle size on reactor kinetics. It is possible to use a third column to investigate biological catalysis, using the enzyme invertase, and compare this with chemical catalysis
