Liquids Research Limited produce ferrofluids based on ferrite and metal particles. A wide range of ready made and custom made magneto-rheological dispersions are also available.


The philosophy of Liquids Research Limited is to supply specialist materials to industry who have an interest in developing new applications for these exciting materials.


As Europe's leading manufacturer of magnetic colloids and related materials, Liquids Research Limited is uniquely placed to provide a comprehensive consultancy service for their clients.


Apart from our standard catalogue products, Liquids Research have a number of client projects underway for development of tailored magnetic fluids, nanoparticles and magnetorheological dispersions.

The Company

Liquids Research Limited, founded in 1990 by Professor K. O’Grady and Dr S. W. Charles, is a leading manufacturer of ferrofluids occupying modern facilities in the Mentec Technology Centre, a science park in Bangor, North Wales.

The founders are internationally recognised as experts in the field of magnetic liquids, ferrofluids, magnetic inks, magnetorheological fluids and bioseparation, leading many research projects covering the fundamental aspects of these materials and other fields also based on fine magnetic particles.

The company is continuously updated on the latest research and development and thus are an obvious choice for consultancy advice in these fields. The founders belong to a number of committees involved with magnetic liquids and are the authors of many original scientific papers.

Ferrofluids and other magnetic composite materials are produced in the company’s well equipped laboratories augmented by access to additional research facilities available locally. In addition to the traditional ferrofluids based on hydrocarbon and diester technology,the company also has available fluids based on perfluoropolyether materials.

The strong research and development base, which is unusual in a small company, enables a fast response in the development of new specialist materials and products required to meet new technological demands.

Bangor is situated in an area of outstanding natural beauty and has good access by road and rail. Manchester International Airport is less than a 90 minute journey via the A55 trunk road which also connects to the UK motorway system.

Current applications for magnetic liquids include:

  • Rotary shaft seals for computer disk drives
  • Rotary shaft seals for vacuum systems
  • Rotary shaft seals for chemicals, gases and radioactive materials
  • Bearing protection from abrasive environments
  • Loudspeaker performance enhancement
  • Magnetic separation of materials
  • Domain observation
  • Ink jet printing
  • Stepper motor dampers
  • Optical switches
  • Inclinometers
  • Cell labelling
