Description
501 20 Ubbelohde viscometer (DIN) is a precision glass capillary instrument calibrated for manual viscosity measurements in the laboratory. It is fitted with capillary number II and a defined constant K = 0,1, enabling accurate determination of the kinematic viscosity of transparent Newtonian liquids in accordance with established DIN procedures. The classic Ubbelohde suspended-level design reduces the influence of filled sample volume on flow time, supporting reproducible results when the measuring temperature is tightly controlled. Supplied as one piece with a net weight of 0,275 kg, the viscometer is intended for use in manual measuring stations and thermostatic baths common in analytical laboratories. This model from manufacturer SI Analytics - a Xylem brand belongs to the 501 series of capillary viscometers used for routine quality control and research. Typical applications include characterisation of oils, fuels, polymer solutions, solvents and other low- to medium-viscosity fluids where manual Ubbelohde methodology is specified. The clearly stated capillary constant simplifies conversion of measured efflux times into viscosity values, while the DIN-compliant geometry ensures compatibility with standard laboratory protocols and reference methods.

Questions about 501 20, Ubbelohde viscometer (DIN), calibrated for manual measurements,
What is this article?
501 20, 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 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.
