Mindex Ltd working as agents for Ravenfield Designs is a dedicated company which specialises in the design & manufacture of scientific instruments. We have a global customer base which includes major oil companies and world class universities. Our main products are viscometers for the oil industry.

We supply a range of ancillary equipment for our own viscometers and other industry standard rotational viscometers. We have recently branched into the biomedical field with our Model EM Shear Generator. This instrument has been developed to apply known shear to a sample while allowing reagents to be added. Observation mechanisms for forward scattering, epifluorescence etc. can be provided

Our latest development for the biomedical market is the Ravenfield Model FB range of Dental Alginate Test Equipment which has been designed to meet the test requirements of ISO 1563. The behaviour of molten metal under shear has also come to our attention as we were commissioned to design and develop a bench rig for investigating molten aluminium alloys. Our Model EO Metallurgical Viscometer is now available. For measurements up to 1750 degrees C we offer our Model FG Ultra High Temperature Viscometer.
