Ravenfield Laboratory
Equipment "Specialist in the design and manufacture of Scientific
instruments" -
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.
