Viscometry

Brookfield DV2T Viscometer [SOP]
Measurement Range: 15-6,000,000 centipoise (cP)
Spec 2: Details

Viscosity

Viscosity is a quantity that numerically describes the resistance to flow of a fluid.

Operation

The viscometer rotates a spindle submerged in the fluid of interest through a spring, which measures the drag caused by the fluid. Factors determining the viscosity measurement are the spindle being used (chosen for its size), the container (this viscometer is calibrated for 600 milliliter low-form Griffin beakers), and the speed of the spindle. Prior to starting a test, the user can select a combination of spindle and rotation speed that best suits their needs and the expected viscosity of the fluid being measured. The viscometer will automatically update the maximum viscosity it can accurately measure with the selected parameters as the user changes the options (i.e. selecting a smaller spindle and/or lowering the speed will increase the range).
