Overview
The Benson Viscometers Ltd BV200 clinical viscometer is a capillary viscometer for in vitro use in the
laboratory, designed and calibrated to measure the viscosity of human (or animal) blood plasma and
other clinical fluids. The BV200 is manually loaded and unloaded with blood samples and reagent
tubes. The operation is automated so that it measures patient samples and carries out automated
check quality controls every ten patient samples without manual intervention offering a walk away
operation.
It is intended for use in clinical laboratories by trained laboratory professionals testing potentially high-
risk blood samples, so it is designed to handle bio-hazardous materials safely.
All equipment is manufactured, produced and supplied by Benson Viscometers Ltd, in the UK. Only
reagents and viscometer cleaning products that are produced and supplied by Benson Viscometers
are to be used with the analyser.
The key clinical applications are in the identification and monitoring of chronic inflammatory
conditions, for example rheumatoid arthritis and in the monitoring of malignancies of the immune
system, e.g. myeloma and to determining hyperviscosity.
