The BV200 is the leading plasma viscometer for clinical use in the UK and Ireland, with over 60 systems currently being operated in hospital laboratories.

The analyser is a capillary viscometer using precisely controlled vacuum to suck samples through the system.

With the Benson BV200 there is no need to take additional blood samples; the plasma viscosity measurement can be performed on the same blood collection tubes used for full blood count, since it needs only 50 micro-litres of plasma.

The BV200 automated multi-sampling plasma viscometer calculates the PV of samples within 30 seconds of the tube being detected by the system. It displays the result on the analyser PC, and automatically makes the information available for uploading to the LIMS system via interfacing software.

For the busy laboratory, this load-and-walk-away system saves time and eliminates many manual errors. The automated bar code facility, 'through the cap' sample aspiration, and computerised results transmission removes the dependency on senior laboratory personnel.

Is compatible with all leading blood collection tube manufacturers (Greiner, Becton Dickinson, Sarstedt).

It can operate either stand-alone or can be interfaced to a network (LIMS).

Samples are tested at 37°C and reported either at 25°C or 37°C.

The software runs on Windows PC (XP, Windows 7)

The BV200 is the UK's system of choice for plasma viscometry screening of all inflammatory conditions.

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.

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.

Some PV Facts
  • Patient plasma viscosity (PV) is unaffected by patient anaemia or polycythaemia 
  • Samples can be analysed up to one week after centrifugation 
  • Test results are not affected by anti-inflammatory drugs 
  • Patient PV is not affected by age (>3 years), gender or smoking 
  • A rise of PV in the third trimester of pregnancy is predictable 
  • The only diagnostic test for plasma hyperviscosity
