Lloyd Instruments, a unit of Largo, Fla.-based Ametek Measurement Calibration Technologies, reports
its compact Davenport™ PETPlus Intrinsic Viscosity (IV) Measurement Instrument for calculating the
IV of polyethylene terephthalate (PET) polymers accurately measures the degradation factor and
furnishes the mean and standard deviation for each polymer batch tested, while eliminating costs
and environmental dangers associated with toxic solvent handling and disposal.
The device, which requires only a power source and pressurized nitrogen supply, functions as
a stand-alone instrument or in conjunction with Ametek’s NexygenPlus PET data analysis software,
and tests polymers without using solvents at virtually all production stages, storing up to 600
test results. Sample preparation equipment such as vacuum pumps and polymer dryers also is
available.
