Beschreibung
536 21 Micro Ubbelohde viscometer (DIN) is a calibrated glass capillary instrument designed for manual kinematic viscosity determination. It features capillary number IIa and a constant K of 0,5, allowing precise measurement of flow times with limited sample volumes while meeting DIN specifications. This micro Ubbelohde viscometer is suited to quality-control laboratories, research facilities and industrial environments that require reproducible viscosity data for Newtonian fluids. Delivered as 1 pc with a net weight of 0,275 kg, the unit is prepared for integration into conventional manual timing setups based on gravity-driven capillary flow. Manufactured by SI Analytics - a Xylem brand, the 536 21 model forms part of a recognised range of precision capillary viscometers. The micro format lowers sample demand without compromising the established Ubbelohde measuring principle. Typical applications include characterisation of polymers, oils, solvents and related liquids under temperature-controlled conditions, where the defined constant K of 0,5 simplifies conversion of observed efflux times into kinematic viscosity results for both routine and specialised analytical work.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 536 21, Micro-Ubbelohde viscometer (DIN), calibrated for manual measurements,
What is this article?
536 21, Micro-Ubbelohde viscometer (DIN), calibrated for manual 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 Präzisionsinstrumente.
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.
