The reactors use the saponification reaction between ethyl acetate and sodium hydroxide. This provides a well understood and safe reaction for the students to investigate the different reactor types.
This is a reactor system specially designed to perform batch enzyme reaction utilizing the glucose isomerisation reaction catalyze by glucose isomerase. The unit is used to demonstrate batch enzyme kinetics and enzyme characteristics.
The fourth reactor - stirred tank reactor in series - is mounted on a dedicated unit.
Developed a set of algorithms which link the degree of conversions of the reactants to the electrical conductivity of the product. In this way the progress of the reaction can be monitored in real time, without the inconvenience and innaccuracy of titration methods.
Features:
Real time reaction monitoring
Small bench top equipment
Safe and student friendly
Four different types of reactor
Data logging facility available
Cost effective - 3 reactors share same service unit.
The Batch Fludized Bed Driercis a small but technologically advanced fluidized bed drier. It allows to directly obtain the characteristic drying curve (CDC), which is used to preset precise parameters on industrial drying plants also of different type such as: cabinets, conveyor plants, rotary. It is suitable to carry out research and small batch production in processes on fluidized materials such as drying, granulation, coatings, etc.

All vessels, pipes, valves and fittings in contact with process materials are constructed in stainless steel with the exception of the borosilicate glass solvent condenser. The support framework is also stainless steel. The vessel base is equipped with an indirect steam chest for process heating. Direct steam is injected at a variable rate through a distribution pipe positioned above the mesh. A similar distribution pipe positioned near the top of the vessel allows solvent to be sprayed uniformly onto the bed of material.
The cylindrical extractor/desolventiser with a hinged lid for charging the extraction material, has a base inclined slightly towards a port for discharging the extracted and desolventised meal. The miscella tank, positioned directly below the extractor to collect the draining liquid, is also a cylindrical vessel incorporating a steam chest as its base. Material is supported above the base by a perforated plate covered with a fine woven mesh so solvent may drain through to the miscella tank whilst retaining the solids.
Vapour from the vessels, produced in the desolventising process,is directed by ducting to the solvent condenser, an inclined cylindrical glass tube containing a double coil through which cooling water is circulated. This vessel also incorporates a direct steam distribution pipe through which steam can be metered at a variable rate. Condensate (usually a mixture of solvent and water) drains into the solvent water separator tank which allows thorough separation of the solvent and water by a gravity process.
It consists of box , spring and connectors used for holding NO.1 battery, which is made of ABS.
The size: 80*36*30mm,it can be series connected, as well as paralleling.
