BROOKFIELD VISCOMETER RVT PDF

We provide a full service. Brookfield viscosity usually refers to a viscosity measurement performed with a Brookfield Viscometer, sometimes refered to as a Brookfield viscosimeter. There are several models of viscometer available from Brookfield but the majority operate in the same manner: the viscometer motor rotates the spindle at a defined speed measured in rpm or shear rate and the viscometer measures the resistance to rotation and reports a viscosity value. Various spindle designs can be employed, depending on the nature of the sample and the requirements. A sample of - ml in a suitable container is placed under the viscometer which is then lowered to dip the spindle into the sample up to an immersion mark on the spindle shaft.

We provide a full service. Brookfield viscosity usually refers to a viscosity measurement performed with a Brookfield Viscometer, sometimes refered to as a Brookfield viscosimeter. There are several models of viscometer available from Brookfield but the majority operate in the same manner: the viscometer motor rotates the spindle at a defined speed measured in rpm or shear rate and the viscometer measures the resistance to rotation and reports a viscosity value.

Various spindle designs can be employed, depending on the nature of the sample and the requirements. A sample of - ml in a suitable container is placed under the viscometer which is then lowered to dip the spindle into the sample up to an immersion mark on the spindle shaft. The dip-in spindle is suitable for comparative testing of the viscosity of free-flowing fluids. In the small sample adapter a small sample typical only 5 - 10ml is sheared between the moving inner cylinder and stationary outer cylinder or chamber.

Ultra Low Adapter ULA The ULA is nothing more than a large concentric cylinder designed specifically for bringing lower viscosity liquids into the measuring range of the viscometer. T-Bar and Helipath This accessory enables the viscometer to take measurements of soft solids such as pastes, creams and ointments.

The Helipath system is a special stand that incorporates a motor that can slowly drive the head of the viscometer down. At the same time the viscometer motor is set to rotate at a low rate typically 2 - 5 rpm and the downward motion of the head causes the t-bar spindle to cut a helical path down through the sample.

Best practice here is to take several measurements over a period of 30 to 60s and take an average. So which is the right one?
