Lloyd Instruments Unveils Davenport™ PETPlus IV Tool

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.
