Relative viscometer.The company's relative viscometer viscometer Instrument for measuring the viscosity (resistance to internal flow) of a fluid. In one type, the time taken for a given volume of fluid to flow through an opening is recorded. is said to provide fast, accurate and precise analyis of dilute polymer solutions for relative, intrinsic, inherent, specific and absolute viscosity, as well as molecular weight. Typical applications include polyethylene terephthalate Ter`eph´tha`late n. 1. (Chem.) A salt of terephthalic acid. , polyvinyl chloride polyvinyl chloride (PVC), thermoplastic that is a polymer of vinyl chloride. Resins of polyvinyl chloride are hard, but with the addition of plasticizers a flexible, elastic plastic can be made. , polyolefins, hyaluronic acid and many others. The relative viscometer is ASTM ASTM abbr. American Society for Testing and Materials approved and can be mated with an autosampler system and other various levels of automation. It is said to provide faster analysis than conventional glass tubes, and yields higher accuracy and precision, according to the company. (Viscotek) Circle 106 on card |
