Features
The miniAV bath unit housing is only 10 inches wide, and the unit is less than 21 inches in height. Modular side panels swivel out for convenient maintenance/service. 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 that also contains temperature and fluid level sensors, optional TE cooling device (required for testing below 40°C), heating element, and impellers that circulate bath fluid to ensure high temperature uniformity.
Like its fully-automatic cousins in the CAV 2000 Series, the miniAV offers selectable temperatures between 20° and 100°C. Data is transmitted to and from the controlling computer via an RS-232 or RS-485 serial interface.
The instrument is shipped with the VISCPRO II controlling software, external power supply, and waste receiver assembly. Convenient chromatography type container lids may be used for connecting cap thread #38 reagent bottles to the miniAV.

Affordable D 445 Automation
The miniAVTM from CANNON Instrument Company offers every laboratory an exciting new tool for convenient and highly accurate kinematic viscosity (Kin Vis) measurement. Occupying roughly the same footprint as a tabletop rotational viscometer, the miniAV automates the time-consuming sample measurement and viscometer tube wash/dry procedures associated with the ASTM D 445 method, freeing the laboratory technician for other duties. The miniAV has been designed as an affordable alternative to traditional labor-intensive manual Kin Vis measurement methods, and provides a first step toward full laboratory automation.
The miniAV performs in tandem with the proven VISCPRO® II software for Windows® XP, providing convenient sample ID data entry, database maintenance, and powerful reporting and LIMS connectivity capabilities. Two miniAVTM instruments can be connected to a single PC to easily determine Viscosity Index for a sample.
Operation
Operation of the miniAV is simple. The user fills the sample vial, places it in the vial holder beneath the viscometer, and raises it into position. Sample ID information is entered via the computer. The user initiates the test with a single mouse click. Without further operator intervention, the sample is drawn up into the viscometer tube, held for temperature equilibration, and then measured. Data is automatically transferred to the computer database via the RS-232 serial connection. 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. Following tube drying, the vial holder is lowered to its original position, ready to receive the next sample. Total cycle time for a test is 3 to 5 minutes depending on the viscosity.
