The miniAV from CANNON Instrument Company offers every laboratory an exciting new tool for convenient and highly accurate kinematic viscosity measurement.
Occupying roughly the same footprint as a tabletop rotational viscometer, the miniAV-X® automates the time-consuming sample measurement and viscometer tube wash/dry procedures associated with the ASTM D445 method, freeing the laboratory technician for other duties.
The miniAV performs in tandem with the proven VISCPRO® II software for Windows®, providing convenient sample ID data entry, database maintenance, and powerful reporting and LIMS connectivity capabilities.
Operation
Operation of the miniAV is simple.
The user fills the sample vials and then places them into a numbered carousel beneath the viscometer.
Sample ID information is entered via the computer. The user initiates the test with a single mouse click.
Without further operator involvement, the sample is drawn into the viscometer tube, held for temperature equilibration, and then measured.
Data is transferred to the computer database.
The sample is then ejected as waste, and the sample vial becomes a wash station as solvent is automatically metered into the viscometer tube and then evacuated to complete the cleaning cycle.
Il solvente viene dosato automaticamente nel capillare e poi evacuato per completare il ciclo di pulizia.
Following tube drying, the vial is lowered and placed in its original position.
The next sample is automatically advanced to a position directly under the viscometer tube.
This sequence is repeated until all 10 tests are complete. Total cycle time for each test is 3 to 5 minutes depending on the viscosity.
Connect two miniAVs to a single PC to easily determine Viscosity Index for a sample.
Up to four miniAV-X®s may be controlled by a single PC.
Accuracy
The miniAV provides automatic kinematic viscosity testing within parameters specified by ASTM D445/446 and ISO 3104/3105.
The miniAV-X measures flow rates within ±0.001 second by electronically timing the liquid meniscus as it moves between thermistor timing sensors.
Bath temperature is controlled with accuracy better than ±0.01°C between 20° and 100°, as required by ASTM D445/446.
Thermistor sensors allow dark or opaque liquids to be measured with the same precision as transparent fluids without the need to change tubes.
Unlike non-traditional bench-top instruments which claim D445 correlation, the miniAV is truly a KinVis instrument.
Using a capillary viscometer defined in D446, the miniAV performs equally well on Newtonian materials, fully formulated oils and additives.
Features
Modular side panels swivel out for convenient maintenance/ replacement.
The modified Ubbelohde compound viscometer tube offers a 100-fold viscosity range (easily covering the range of 5 separate manual glass viscometers), and requires only 5 mL of sample (3 mL with Fast-Run tubes).
The tube rests in a 1-liter temperature bath.
The bath also contains temperature and fluid level sensors, optional TE cooling device, heating elements, and an impeller that circulates bath fluid to ensure high temperature uniformity.
Like the fully-automatic high capacity CAV 2000 Series instruments, the miniAV-X offers selectable temperatures between 20° and 100°C.
Data is transmitted to and from the controlling computer via a standard RS-232 serial interface.
The instrument is shipped with the VISCPRO II controlling software, external power supply, and waste receiver assembly.

- Sample heating
- Autosampler (10 positions)
