Is automated DSV set to halt the U-tube trend?

That’s U-tube (Ubbelohde Tube) – not YouTube!

Automated Dilute Solution Viscometry (DSV) systems directly measure the relative viscosity of dilute polymer solutions, allowing the determination of intrinsic viscosity, a parameter that correlates with molecular weight, itself a defining polymer characteristic. Safer, and more accurate than  traditional glassware methods it is easy to find yourself wondering why anyone wouldn’t want to switch to an automated system.

Safer….

The Viscotek DSV solution uses advanced pressure sensing technology and ASTM-approved methodology in a closed loop system. It combines automated sample preparation and low solvent consumption with highly accurate true relative viscosity measurement. Self cleaning and  self calibrating, it requires minimal maintenance and reduces the need for human interaction. This means safer operation  – no need to deal with  hazardous (and sometimes hot) solvents – less potential for human error, and maximum analytical  throughput.

….and widely applicable

Capable of automated, highly sensitive and precise measurements of samples in a wide variety of solvents, with options for high temperature measurement, the Viscotek DSV solution offers application flexibility.  Common applications include tricky to handle polymers such as Polyethylene (PE) or Polypropylene (PP) that need to be dissolved in Decalin or Tetralin, as well as a wide range of other materials such as Polyvinyl Chloride (PVC), Nylon,  Hyaluronic Acid and Cellulosics, among others.
