Faster analysis, greater precision and less solvent exposure than the traditional Ubbelohde or Cannon-Fenske glass tube viscometers
The model Y501C relative viscometer from Viscotek is, says the company, the benchmark analytical tool used by a growing number of leading chemical companies worldwide to measure the viscosities of dilute polymer solutions.
The Y501C measures solvent and sample viscosity simultaneously, avoiding errors due to temperature fluctuations and solvent variations.
The system provides faster analysis, greater precision and less solvent exposure when compared to the traditional Ubbelohde or Cannon-Fenske glass tube viscometers that it replaces.
The Y501C is said to be the only solution viscometer that can provide relative, intrinsic, inherent, specific and absolute viscosity as well as molecular weight information from a single experiment. Fully compliant with ASTM method D5225-92 (solution viscometry of polymers) the Y501C offers three levels of automation to suit both budget and sample throughput requirement.
Installed at production facilities throughout North America and Europe the Y501C has helped many companies dramatically improve inherent viscosity measurements.
The system has typically provided accurate results on only a 1% solution, which has made it possible to reduce sample preparation time significantly.
This substantial reduction in the amount of time required to measure viscosity has facilitated much more timely feedback on process variables, resulting in increased polymer production yields.
The Y501C is proven for the analysis of polymers including polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyolefins (PE, PP), polyamides (nylon), synthetic rubbers (EPDM) and hyaluronic acid (HA).
