Falling-Sphere Viscometer Analytical Service

Overview

The Falling Sphere Viscometer measures fluid viscosity by observing the descent of a sphere through the fluid under gravity. Based on Stokes' law, the sphere's terminal velocity is used to calculate the viscosity, considering the densities of the sphere and fluid, as well as the sphere's size. This simple and accurate method is suitable for low- to medium-viscosity fluids and requires minimal equipment.

Sample Requirements

• The sample must be a homogeneous fluid at room temperature and within the measured temperature range. Strongly acidic, alkaline, or highly corrosive liquids are not permitted.
• Samples should be easily soluble in water or ethanol. For samples soluble in other complex solvents, please contact in advance.
• Required sample volume: 10 mL, sealed for preservation. Standard testing is conducted at room temperature.
• Density Range: 0–3 g/cm³
• Viscosity Range: 0.3–1000 mPa·s
• Measurable Temperature Range: 10–90°C
