RPV-1<\/a> (2) Auto PP<\/a>\/PE<\/a>
\n<\/span><\/p>\n

The PSL Rheotek RPV-1 (2) AutoPP \u2013 two position PP\/PE viscometer is specially adapted for measuring polyethylenes (PE) and polypropylenes (PP) at 135 \u00b0C. Suitable for low and medium density samples.<\/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 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) AutoPP 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 PP\/PE, 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
