IVA Instrument, Polymer Characterization, S.A., (CAT#: STEM-LE-0935-LC)

The introduction of IVA by Polymer Char is in response to the market demand for reliable automated instruments for intrinsic viscosity analysis of polymer materials in solution. Intrinsic viscosity can be viewed as an indirect measure of average molar mass, therefore, it can provide valuable information in any polymer characterization process. IVA is based on Polymer Char's recently developed QC platform, which integrates a rugged dual capillary relative viscometer and a high-temperature autosampler that can hold 42 samples in a reduced footprint. By using almost any organic solvent, IVA can analyze various polymers with IV values from 0.5dL/g to over 40dL/g, such as polyolefin, PET, PAN, PMMA, etc.
