Semi micro Ubbelohde viscometerIt is a precision instrument used to measure the viscosity of small amounts of liquid samples, widely used for the determination of the molecular weight of organic matter polymers and the determination of the viscosity of various other liquids.

The semi micro Ubbelohde viscometer measures the viscosity value of a liquid by utilizing the internal friction generated when it flows in a capillary tube. When a liquid flows in a capillary under the action of gravity, the flow velocity is inversely proportional to the viscosity. By accurately measuring the time required for the liquid to flow through a specific marked line on the capillary, combined with the geometric parameters of the capillary, the kinematic viscosity of the liquid can be calculated.
