PET Intrinsic Viscosity Tester Automatic Viscometer

Automatic capillary viscometer for intrinsic viscosity of PET resin and preforms in a thermostatic bath. Used by preform makers to check molecular weight and degradation during drying and molding.

Specification

PET is dissolved in a solvent mixture and flow time is measured through a Ubbelohde capillary in a thermostatic bath. Intrinsic viscosity is calculated from solution and solvent times. It reveals degradation during drying and molding.

Features

• Constant temperature bath 25 deg C
• Automatic flow time detection
• Ubbelohde capillary
• Auto calculation of IV
• Stirrer included
