- This Intrinsic Viscosity Analyzer is a new concept that focuses on improving the accuracy and reproducibility of the results thanks to the combination of specific features. The automation of the entire process eliminates human error. The integrity of samples is preserved throughout the analysis for more accurate values. Both solvent and polymer are simultaneously measured by two capillaries for increased consistency. The air-tight design eliminates cold spots, which is especially useful for analyzing High and Ultra-high molar mass polymers.

-IVA Versa doesn't require adding several modules for the complete process automation, including sample dissolution and cleaning. Everything is integrated into the system, making it a compact and cost-effective unit that will not require future purchases of separate pieces.

-The IVA method complies with the ASTM D5225 Standard Test Method for Measuring Solution Viscosity of Polymers with a Differential Viscometer, and it's currently being included in the ISO 1628-1 as an alternative to the current method based on Ubbelohde glass capillaries.
