Ubbelohde viscometer is professional capillary glass instrument specially designed for petroleum laboratory viscosity testing, complying with ASTM standard. Made of high transparent borosilicate glass with precise calibrated capillary and timing scale. It adopts suspended level structure to eliminate liquid level influence, realizing accurate kinematic viscosity measurement of petroleum and transparent Newtonian liquid. Stable glass performance avoids deformation under constant temperature water bath. Simple operation, small sample consumption, accurate test data and good repeatability. Widely used in petroleum detection, chemical raw material analysis and polymer solution viscosity determination labs.
