Essential Automation for Polymer Solution Viscosity
The miniPV®-HX from CANNON Instrument Company is an essential tool for the measurement of polymer solution viscosities. Its accuracy and convenience are based on the masterful design of temperature control, fluid handling, sensor technology, and automation. Complete control of the instrument is provided through VISCPRO II software (for Windows®) which also facilitates procedural tasks such as calibration, data entry, method specification, calculation selection, report formatting, and data exporting. The miniPV®-HX occupies roughly the same footprint as an analytical balance, yet is able to provide a high level of automation which includes sample loading, temperature equilibration, flow time measurement, and cleaning of the entire system between measurements. VISCPRO II is unique in its ability to perform an automatic Huggins-Kraemer determination of intrinsic viscosity in addition to single-point methods based on Billmeyer and on Solomon-Ciuta. Multiple viscosity calculations are also available, leading to relative, inherent, and reduced viscosity determinations. In addition, the software provides flexible and sophisticated control of data export options and database management.
Samples are prepared using optional Cannon Instrument SPS Sample Preparation System in reusable or disposable sample vial. The samples are inserted into the multiple position auto carousel. The user then selects start. This action initiates the sample loading procedure and the subsequent series of automatic processes that were specified by the user in the VISCPRO II method parameters. In general, the sample is drawn into the viscometer tube, held until the temperature has equilibrated, and then released to drain during automatic timing of the flow rate. Data is transferred via the RS-232 serial connection to a host computer that stores and maintains the data in a database. The sample is then ejected as waste and the sample vial becomes a wash station as solvent is automatically injected into the viscometer tube to initiate the cleaning cycle. The user may select to run a second solvent for a subsequent rinse and a final purge of compressed air during the wash cycle. Following tube drying, the sample carousel advances to the next position and repeats the automation process.
