Benson Viscometers Support

Benson Viscometers pride themselves on the support and maintenance of the BV200 or BV1 plasma viscometers.

This section contains mainly software downloads, which users can download and install. It is suggested you contact the support desk before updating any software, to check the version will work on your system.

About PV

Benson Viscometers Ltd is a British company that manufactures, distributes and maintains a range of clinical viscometers, tuned to analyse blood plasma viscosity.

The range includes a fully automated walk away high volume analyser (BV200) capable of processing 60 samples per hour for large laboratories and a semi automated analyser (BV1) suitable for small laboratories performing up to 50 samples a day.

The company also supplies a full range of control and maintenance reagents to give operators confidence in their results.


BV1 Unit
For confidence in your results

An increasing number of laboratories are electing to use Plasma Viscosity routinely in preference to erythrocyte sedimentation testing (ESR). This is because Plasma Viscosity results are easier to imterpret and results can be fully validated.

What They Say

"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 footprint. Customer support is second to none." Graham Gibbs MSc CSci FIBMS, Lead Biomedical Scientist, Haematology Dept., Musgrove Park Hospital.
