Description
545 23 Ubbelohde viscometer (ASTM) is a precision capillary instrument calibrated for automatic viscosity measurements in laboratory environments. Equipped with capillary number 2C and a constant K of 0,3, it supports accurate determination of kinematic viscosity in accordance with ASTM methods. The design includes an integrated filling and cleaning tube that simplifies sample introduction and subsequent cleaning between runs. Supplied as a single piece with a net weight of 0,34 kg, the instrument carries the AVS® registered trademark and is intended for use with automated measuring systems. This model from manufacturer SI Analytics - a Xylem brand is well suited to quality-control, research and routine testing workflows where reproducible suspended-level measurements are required. The Ubbelohde geometry provides temperature-independent results within the viscosity range corresponding to the selected capillary, making the 545 23 a reliable choice for laboratories that integrate glass capillary viscometers into automatic platforms. Its robust construction and factory calibration ensure consistent performance for both aqueous and organic samples under controlled conditions.

What is this article?
545 23, 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.
