Description
Ubbelohde viscometer 10-100 mm²/s is a DIN-type capillary instrument for determining the kinematic viscosity of transparent liquids. It features a printed constant in accordance with ISO/DIN 3105, DIN 51502 and BS 188, and is specified as KFT 60-100 size No. II. The capillary has an internal diameter of 1,13 mm and constant K 0,1, covering the measuring range 10-100 mm²/s. Supplied uncalibrated in a four-limb configuration, the glass apparatus supports precise efflux-time measurements under controlled temperature conditions. This model from manufacturer Witeg is intended for routine laboratory viscosity work, quality control and research applications that require reliable results within the stated range. The DIN-compliant design with printed constant simplifies calculation of kinematic viscosity from observed flow times. Offered as a single piece with a net weight of 0,115 kg, it integrates readily into standard viscosity test setups used in analytical and industrial laboratories.

Questions about Ubbelohde viscometer 10-100mm²/s
What is this article?
Ubbelohde viscometer 10-100mm²/s is the article on this page. Luminix Health distributes Witeg 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.
