Our analyser is able to measure the viscosity of human biological fluids: blood plasma, blood serum, whole blood and synovial fluid. Plasma samples can be used as an effective, stable diagnostic tool to screen and monitor patients for conditions that include rheumatoid arthritis, myeloma and plasma hyperviscosity. The BV1 also provides consistent, accurate results with the aid of regular quality control samples. Network interface capability adds essential traceability and records that can be easily accessed using our in-house software.
In addition to this, our clinical viscometers have a very fast turnaround time with minimal downtime, as automated cleaning cycles are performed between each blood plasma sample. To reduce biohazard risks the test samples are directly taken from full blood count tubes and can eliminate the need for additional samples to be taken from adult or paediatric patients.
The portable and compact nature of our viscometer means it can easily be integrated into busy laboratories. Patient confidentiality is maintained as our machines only store the barcode number. The machine requires an operator login and password, ensuring that only trained and qualified personnel are able to access the viscometer.
Benson Viscometers are flexible in our approach to supplying calibration and specialist cleaning reagents. We are able to map out the specific requirements for these products which can be supplied by contract or on an ad-hoc basis as required.
The operation of the BV1 is simple and effective. An overview of the process is as follows.
- The BV1 clinical viscometer will measure the viscosity of human biological fluids: blood plasma, blood serum, whole blood, and synovial fluid
- The BV1 analyser is ideal for processing up to 50 patient samples a day
- It will test directly from primary blood sample tubes reducing biohazard risks
- Uses the residue from the full blood count tubes eliminating additional sample requirements
- Through cap piercing capability reducing biohazard risks tubes, eliminating additional samples
- Accommodates tubes from all leading blood collection tube manufacturers
- Aspirates only 60µl per test. Only requires 500µl of sample fluid
- Therefore, it is suitable for repeat testing of paediatric and adult samples
- Fast, 15-minute turnaround time from sample receipt to results
- Barcode reading immediately prior to analysis
- Operator is present to process patient test samples
- Automated calibration checks every 6 patient samples
- Network interface capability
- Sample and wash carry-over level of <0.01 mPa.s
- Tests at 37°C, reports at 25°C or 37°C
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 primarily 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 operator must attend the analyser to load un-tested patient samples and controls and remove tubes that the instrument has processed.
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.
- The BV200 clinical viscometer will measure the viscosity of human biological fluids: blood plasma, blood serum, whole blood and synovial fluid
- The BV200 analyser regularly processes in excess of 400 samples a day
- It will test directly from primary blood sample tubes reducing biohazard risks
- Uses the residue from the full blood count tubes eliminating additional sample requirements
- Through cap piercing capability reducing biohazard risks
- Accommodates tubes from all leading blood collection tube manufacturers
- Aspirates only 50µl per test. Only requires 500µl of sample fluid
- Therefore, it is suitable for repeat testing of paediatric and adult samples
- Can be loaded with up to 180 patient samples at a time
- Fast, 15-minute turnaround time from sample receipt to results
- Automatic barcode reading immediately prior to analysis
- Load and walk away system
- Automatic calibration checks every 10 patient samples
- Network interface capability
- Sample and wash carry-over level of <0.01 mPa.s
- Operator password logon
- Tests at 37°C, reports at 25°C or 37°C
