Description
541 01 Ubbelohde viscometer (DIN) is a calibrated capillary instrument intended for automatic viscosity measurements and equipped with filling and cleaning tube. Specification lists capillary number 0a and constant K = 0,005, placing the model in the low-viscosity working range. The DIN Ubbelohde geometry supports accurate kinematic viscosity determination when used with automated timing systems and controlled temperature baths. Supplied as 1 pc with a net weight of 0,34 kg, the unit is offered by manufacturer SI Analytics - a Xylem brand and is associated with the AVS® registered trademark line. Factory calibration enables straightforward integration into automated measurement sequences, while the filling and cleaning tube facilitates sample loading and intermediate rinsing. Typical uses include low-viscosity polymer solutions, solvents, dilute oils and other Newtonian fluids examined under standardised DIN protocols. Laboratories performing high-throughput or automated viscosity work benefit from the defined capillary constant and accessory tube arrangement, making this model a practical choice for research and quality-control environments that require calibrated Ubbelohde performance at low K values.

What is this article?
541 01, 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.
