Ordering Specification

• A small scale continuous stirred tank reactor with an adjustable volume of 0.4 - 1.5 litres.

• The vessel is equipped with a variable speed square blade turbine agitator with a speed range 0-230rpm.

• The vessel is constructed from borosilicate glass and PVC with stainless steel heat transfer coil and removable reactor baffle.

• Glands are mounted in the lid for fitting appropriate sensors.

• The vessel is mounted on a PVC baseplate which fits directly onto the service unit.

• Demonstration capabilities:
> Determination of reaction rate constant
> Variation of conversion with residence time
> Evaluation of empirical rate expressions from experimental data
> Effect of temperature and mixing efficiency on reaction kinetics

Technical Description

The reactor volume is adjustable with a maximum of 2 litres and a minimum of 1 litres.
The reactor is equipped with a variable speed turbine agitator and baffle arrangement to ensure thorough mixing. A submerged stainless steel coil is used for operating the reactor at different temperatures. Quick release connectors allow easy supply of heat transfer medium to the coil and reagent from the feed pumps of the service unit. Glands in the lid allow fitting of the conductivity and temperature probes of the service unit. Operation at temperatures below ambient is possible.
