Ordering Specification

• A small scale tubular reactor (volume is 0.4 litres) capable of demonstrating large scale behaviour.

• The reactor coil is mounted in a clear acrylic vessel through which heating or cooling medium is circulated. Length of reactor coil is 20m.

• Two pre-heat coils bring the reactants up to the reaction temperature separately before they are mixed in a Y piece after which the reaction begins.

• Performance is monitored by a conductivity sensor mounted in a flow cell at the end of the reacor coil.

• Quick release fittings are used for process and service connections to enable quick mounting and removal from the service unit.

• Demonstration capabilities:
> Determination of the rate constant

Technical Description

The Armfield Tubular Reactor or 'plug flow' reactor is in the form of a tube wrapped in a spiral around an acrylic former which is enclosed in a transparent tank. Water at a controlled temperature is circulated within the tank, this maintains the reactants at constant temperatures. Reagents are separately piped to the reactor through quick release fittings mounted on the lid. Reagents are pre-heated in stainless steel coils before being mixed and loaded into the reactor coil.
