Description
The 541 43 Ubbelohde viscometer (DIN) is a precision capillary instrument calibrated for automatic measurements of kinematic viscosity. It features capillary number IVc together with a viscometer constant K = 30, matching the higher viscosity range defined for this DIN capillary. An integrated filling and cleaning tube allows straightforward sample introduction and effective rinsing between runs, supporting efficient laboratory procedures. The instrument is supplied as a single piece with a net weight of 0,34 kg and is designed for use in automatic measuring systems. This model from manufacturer SI Analytics - a Xylem brand delivers standardised Ubbelohde geometry for quality-control, research and routine analytical applications. Calibrated capillary dimensions ensure reproducible flow-time data, while the dedicated filling and cleaning tube simplifies handling and maintenance. Laboratories needing reliable DIN-compliant viscosity determinations benefit from the defined constant K = 30 and the practical construction of this automatic-ready Ubbelohde viscometer.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
541 43, Ubbelohde viscometer (DIN), 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.
