Description
The 527 03 Ubbelohde viscometer (ASTM) is a precision glass capillary instrument calibrated for automatic measurements, equipped with capillary number 0C and constant K = 0,003. It enables accurate determination of kinematic viscosity for transparent Newtonian liquids according to ASTM protocols and is intended for integration into automated laboratory systems. Supplied as 1 pc with a net weight of 0,346 kg, the unit supports efficient, reproducible viscosity testing in research and quality-control environments. Manufactured by SI Analytics - a Xylem brand, this Ubbelohde design uses the suspended-level principle to minimise sample-volume effects and deliver consistent results. The capillary constant of 0,003 is suited to lower viscosity ranges commonly encountered in chemical, petrochemical and materials laboratories. Calibration for automatic operation removes the need for manual timing, streamlining workflows while maintaining high measurement reliability. The instrument is well matched to routine and advanced applications that require ASTM-compliant data and compatibility with automated viscometry setups.

Questions about 527 03, Ubbelohde viscometer (ASTM), calibrated for automatic measurements,
What is this article?
527 03, Ubbelohde viscometer (ASTM), calibrated for automatic measurements, 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.
