Ubbelohde Viscometer for transparent liquids

Measures viscosity of transparent liquids using a suspended-level capillary design, minimizing flow errors and ensuring accurate, temperature-stable results.

Ubbelohde Viscometer for transparent liquids

Ubbelohde Viscometer as per Astm D446 for Transparent liquids - Calibrated 

An Ubbelohde type viscometer is a capillary type viscometer which uses a capillary based method of measuring viscosity.It is recommended for higher viscosity polymer and other relevant solutions. A liquid is introduced into the reservoir then sucked through the capillary and measuring bulb. The liquid is allowed to travel back through the measuring bulb and the time it takes for the liquid to pass through two calibrated marks is a measure for viscosity.
