In the late 1990’s, I worked together with respected scientists and haematologists from the UK NHS to develop a game changing laboratory instrument. Originally known as ‘The Blood Plasma Viscometer’, and now ‘The Automated Clinical Viscometer’. Our clinical analysers continue to support your critical work with accuracy and efficiency.”
History
Built for Clinical Performance
Since 1999, our British company has focused on one thing: delivering the most reliable clinical viscosity testing in the world.
Enabling Better Patient Outcomes
Clinical viscosity testing is increasingly recognised as a vital biomarker in clinical diagnostics, especially for identifying high-risk patients in conditions like Rheumatoid Arthritis, Multiple Myeloma, Waldenström’s Macroglobulinemia, Hyperviscosity Syndrome, Temporal Arteritis, Cardiovascular Disease and many more. That’s why many of the leading healthcare institutions in the UK, USA and Europe trust Benson Viscometers to support their patient care.
Global Trust, Local Care
With a growing footprint across the UK, Europe, and the USA, Benson Viscometers is proud to be the name behind clinical viscosity measurement in some of the world’s most respected healthcare systems.
Certified to Support You
We are FDA registered and hold ISO 9001:2015 and ISO 13485:2016 certifications, reflecting our dedication to quality and compliance.

Our Benson BV200 is serviced on a bi-annual basis by one of the Benson Viscometer service engineers. We are a remote Hospital site situated in the Scottish Highlands which makes emergency call out for an engineer quite difficult. However, this is compensated by an enhanced telephone service from the Benson support team. This includes personnel who have a massive in depth knowledge of their technology as well as dedicated IT support. The team work together as required to resolve any issue, providing clear instruction and computer upgrades as necessary. Any required parts for our BV200 are sent by dedicated delivery - if the Benson helpdesk are aware in good time on any given day replacement parts will be sent promptly and normally received the following day - exceptional for our geographical location.
Mick Milner, Haematology Team Manager, Blood Science Dept., Raigmore Hospital, Inverness.
I would like to say how reliable our BV1 has proved over the years and how helpful the Benson staff are on the very odd occasion when there is a problem.
Erica Stewart, Haematology Laboratory, Ulster Hospital
Benson Viscometers is the UK leader for plasma viscosity testing systems and we have had a long relationship with Bernie Benson. The BV1 is superbly engineered and easy to use, with a modified PC cabinet and a small foot print. Customer support is second to none.
