BROOKFIELD DV-II+ Pro PROGRAMMABLE VISCOMETER

The Brookfield DV-II+Pro Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid’s resistance to flow. You will find a detailed description of the science of viscosity in the Brookfield publication “More Solutions to Sticky Problems” a copy of which was included with your DV-II+Pro.

function called the free energy. Thermodynamics tells us that: Equilibrium and Metastable States • Under conditions of a constant temperature and pressure and composition, the direction of any spontaneous change is toward a lower free energy. • The state of stable thermodynamic equilibrium is the one with minimum free energy.

- Shear for samples with a shear modu-lus in a very large range from about 1 kPa to 2 GPa. This allows viscous liquids and even solid samples, e.g. polymers in the glassy state, to be measured. - Three-point bending for stiff samples with a modulus of elasticity of up to 1000 GPa. - Single and dual cantilever bending

DSC Measurement of Polypropylene - Hitachi High-Tech

Figure 1 shows the DSC curves for measurement condition 1. All samples showed an endothermic peak due to PP melting around 160℃. Furthermore, on the low temperature side of the endothermic peak, the untreated sample showed a smooth DSC curve between 110 and 125℃ while the treated samples showed a minute peak.
