Ubbelohde viscometer is a measuring instrument which uses a capillary based method of measuring viscosity.It is recommended for higher viscosity cellulosic polymer solutions. The advantage of this instrument is that the values obtained are independent of the total volume. 

* Viscometer: measures the kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. The minimum sample volume is 11 mL. The minimum bath depth is 241 millimeters (9.5 inches). The constants of the unified factor series are within the range of+/-0.2% of the listed values. 

* Glass Material: made from borosilicate glass, offer exceptional chemical and heat resistance. 

* High Transparency: Features excellent transparency, allowing easy observation of the internal process and convenient monitoring of the experiment
