My Account Log In. The solution and viscometer are placed in a constant temperature water bath. The limiting value of the reduced viscosity or the inherent viscosity at infinite dilution of the polymer. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure.

ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity.
