Description
545 20 Ubbelohde viscometer (ASTM), calibrated for automatic measurements, is a precision capillary instrument for laboratory determination of kinematic viscosity. It is equipped with capillary no. 2 and constant K = 0,1, together with an integrated filling and cleaning tube that aids sample introduction and rinsing. Designed according to ASTM requirements, the viscometer is calibrated for use in automatic measuring systems. Supplied as 1 pc with a net weight of 0,43 kg, the instrument originates from Germany. The 545 20 model from manufacturer SI Analytics - a Xylem brand carries the registered trademark AVS ® and provides classic Ubbelohde measuring geometry for analytical viscosity workflows. Factory calibration for automatic operation supports reliable flow-time recording through the capillary under controlled conditions. The filling and cleaning tube forms part of the glass assembly, allowing efficient preparation between successive samples. This configuration is suitable where standardised, calibrated Ubbelohde viscometers are needed for routine laboratory work. The stated capillary constant permits calculation of kinematic viscosity once flow times are obtained on compatible automated platforms.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
545 20, Ubbelohde viscometer (ASTM), calibrated for automatic measurements, with is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
