Description
545 13 Ubbelohde viscometer (ASTM), calibrated for automatic measurements, is a precision capillary instrument intended for kinematic viscosity determination. It features capillary no. 1C with constant K = 0,03 and includes an integrated filling and cleaning tube for sample loading and instrument rinsing. Built to ASTM specifications, this Ubbelohde design is calibrated for automatic measuring systems used in analytical laboratories. The single-piece unit has a net weight of 0,34 kg and originates from Germany. Available from manufacturer SI Analytics - a Xylem brand, the 545 13 model carries the registered trademark AVS ® and offers standardised measuring geometry for reproducible flow-time determinations. Factory calibration for automatic operation supports consistent data generation when the instrument is paired with compatible viscosity platforms. The filling and cleaning tube simplifies handling between samples while maintaining the capillary path. This configuration suits laboratories that require calibrated ASTM Ubbelohde viscometers for routine viscosity work. The stated capillary constant enables calculation of kinematic viscosity from measured flow times under defined temperature conditions on automated systems.

What is this article?
545 13, 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.
