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….READ MORE >
