BV200 Automated Clinical Viscometer
The Benson Viscometers BV200 clinical viscometer measures the viscosity of clinical human biological fluids: blood plasma, blood serum, whole blood, and synovial fluid. It is an in-vitro analyser for use in a pathology laboratory environment by trained laboratory professionals.
It is a fully-automated analyser. When the operator has carried out a simple daily maintenance program and initiated the testing procedure it will process patient test samples, calibration, check quality controls, system washing, system enzymatic cleaning and system sterilisation.
The principle of operation of the BV200 is a capillary viscometer that draws a sample of liquid through a temperature controlled (37℃) calibrated capillary tube using a pre-set known force in the form of a regulated vacuum. The time for the fluid to pass two known points is measured and recorded. This ‘runtime’ is used to calculate the dynamic viscosity of the fluid.
The BV200 viscometer can be used with biological fluids that are considered to be bio-hazardous by utilizing the ‘through cap piercing capability’ where the sample tube cap does not need to be removed.
BV1 Semi-Automated Clinical Viscometer
The Benson Viscometers BV1 Clinical Viscometer measures the viscosity of human biological fluids: blood plasma, blood serum, whole blood, and synovial fluid. It is an in-vitro analyser for use in a pathology laboratory environment by trained laboratory professionals.
It is a semi-automated instrument, for which the operator is present to process patient test samples, calibration, check quality controls, system washing, system enzymatic cleaning and system sterilisation.
