This compact, low cost Intrinsic Viscosity (IV) measuring instrument is capable of minimizing both the costs and the environmental hazards associated with the handling and disposal of toxic solvents used in conventional IV testing instrument.
The PETPlus is supplied with a convenient integral nitrogen regulation valve for easy pressure adjustment when testing different materials. Requiring only power and a pressurised nitrogen supply, the instrument can be operated in stand-alone mode or used in conjunction with ‘NEXYGENPlus PET’, the company’s powerful new dedicated data analysis software package for the IV measurement of PET polymers. A user-friendly training mode is included as standard to simplify operator instruction.
Polymers can be tested by the PETPlus at virtually all stages of the production process to provide greater overall control. Tests can be completed in as little as 20 minutes on incoming resin, powder, dry granules, molten polymer, pre-forms, bottles, films and even re-ground material to eliminate scrap. Rapid testing at the different stages can be carried out using ancillary equipment for controlled sample collection and preparation. The instrument’s compact construction occupies significantly less bench space than earlier models and makes it easier and quicker to load samples.
The microprocessor controlled stand-alone system provides high accuracy measurements, temperature control to + 0.1°C and storage of up to 600 test results. A backlit LCD displays instructions for the test in a variety of languages as well as the results. An RS-232 interface allows connection to a computer for downloading of results or for fully automated software control using NEXYGENPlus PET.
The PETPlus Intrinsic Viscosity Measurement Instrument uses a well-established unique solvent-free method for routine IV measurement of PET. Molten PET is extruded through a calibrated die by nitrogen gas under pressure and the LVDT probe movement against time is recorded and displayed. The system measures the optimum flow rate and calculates intrinsic viscosity. The procedure used ensures that reliable, accurate and repeatable results are easily obtained and checked against standard polymers.
A comprehensive range of sample preparation equipment including vacuum pumps and polymer dryers are available to ensure correct sample drying conditions for the instrument. By using the Quick Test Polymer Chip Grinder, the material can be ground to a fine powder to ensure drying within just 50 minutes. A Polymer Chip Transfer Vessel is available to carry dried PET directly from the process dryer to the PETPlus for instant testing.
