Armfield through their CE and UOP range of products offer the most comprehensive, diverse and technically current group of products of any manufacturer, bringing both basic principles and complete unit operations to the modern educational laboratory.
The UOP3 laboratory-based distillation columns allow safe hands-on practical training for student engineers and plant operators. Available as either a continuous distillation column or a batch-only version for teaching the fundamentals.

The UOP4-MkII is a laboratory-scale solid/liquid extractor system for teaching the fundamentals of this important unit operation to chemical-engineering students. The equipment utilises a sophisticated, continuous feed, counter-current flow, multiple-stage, rotary extractor system of the type frequently seen in industrial applications.
Liquid / liquid extraction is an important operation in chemical engineering where the separation of one or more of the components from a liquid mixture is required. Traditionally this has been difficult to demonstrate in the laboratory, requiring the use of highly toxic, expensive and / or environmentally damaging solvents. The Armfield UOP5-MkII introduces a system using kerosene (paraffin) which is simple, safe and inexpensive.
The Armfield Computer Controlled Water Cooling Tower has been designed to give students an appreciation of the construction, design and operational characteristics of a modern evaporative cooling system. The unit is also an excellent example of a specialized heat exchanger, where two streams of fluid flow (water and air) are brought into direct contact and in which there is a mass transfer from one stream to the other.
The Armfield Gas Absorption Column has been designed to demonstrate the principles of gas absorption, and to provide practical training in the operation of a gas absorption plant.
This small-scale benchtop tray dryer dries solids by passing a stream of hot air over trays of wet material, a method commonly used in industry. It is applicable to the unit operations laboratory and also to food technology education and research.
As many laboratories do not incorporate a centralised or reliable steam source, Armfield offer an advanced boiler providing a constant supply of steam. The compact unit requires only connection to water and electrical supplies for operation.
The UOP10 is an advanced boiler, providing a constant, steady supply of steam. The compact unit requires only connection to water and electrical supply for operation.
The UOP20X is a modular system of evaporators for teaching chemical engineering. Using the various modules a wide range of configurations can be implemented: rising or falling film; single or double effect; forward, backward or parallel feed. The evaporators are fully
computer compatible, supplied with educational software including process control and data logging facility.
Each evaporator column contains a stainless steel evaporation tube, within an insulated heated jacket for the hot water or steam. These are mounted on a back plate together with a glass cyclone to separate the concentrated product from the evaporated steam.
Also included on the back plate of each evaporation column is a recirculation pump and associated pipework, together with thermocouples to measure the temperatures of the product and heating fluid at a number of points. Two basic types of evaporation column are available:
UOP22 - Rising Film Evaporation Column
UOP23 - Falling Film Evaporation Column
A number of variants are defined for each column type, dependent on whether it is a first or second effect unit, and whether it is located in the first or the second position on the UOP20X service unit.
