The PSL Rheotek RPV-1 (2) Auto PVC<\/a> two position AutoPVC viscometer system is is configured specifically for fully automating the Reduced Viscosity of Polyamides (PA), nylon, dissolved in m-Cresol in accordance with ISO 307<\/a>.<\/p>\n

Auto systems fully integrate sample preparation, sample dissolution & sample loading, as well as flow time measurement, cleaning and reporting of results. One or two heating and stirring zones can be configured to control the dissolution of batches of samples. Both heating temperatures and stirring times are computer controlled and samples are cooled prior to being automatically loaded into the viscometer. Typical sample throughput is 6 to 8 samples per hour with two measuring positions.<\/p>\n

The PSL Rheotek RPV-1 (2) AutoPA provides a reliable and precise system for measuring dilute solutions of polymers.<\/p>\n

Auto systems not only combine the control of the sample preparation process but also the sample dissolution.<\/p>\n

The RPV Auto system controls the heating and stirring times of polymer solutions, as well as cooling prior to<\/p>\n

measurement.<\/p>\n

Sample dissolution control is critical in order to ensure that polymer solutions, such as PA, do not degrade prior<\/p>\n

to measuring their intrinsic viscosity.<\/p>\n

The RPV-1 Auto automates the manual steps set out in standard methods, minimizing the variability of results.<\/p>\n

Flow times are measured automatically using ASTM Ubbelohde<\/a> viscometer tubes supplied with ISO 17025<\/p>\n

certificates of calibration.<\/p>\n

Cleaning is carried out in-situ utilizing solvents and a safe vacuum system.<\/p>\n

The comprehensive RPV-1 Auto software program records all measurement data as well as calculating a wide<\/p>\n

range of results.<\/p>\n
