Description
Ubbelohde viscometer 30-300 mm²/s is a DIN-type capillary instrument for kinematic viscosity measurement of transparent liquids. It carries a printed constant conforming to ISO/DIN 3105, DIN 51502 and BS 188, and corresponds to KFT 60-100 size No. IIc. The capillary internal diameter is 1,50 mm with constant K 0,3, giving a measuring range of 30-300 mm²/s. Delivered uncalibrated in a four-limb glass design, the instrument enables accurate determination of kinematic viscosity from efflux times under temperature-controlled conditions. This model from manufacturer Witeg is suitable for laboratory quality control, formulation work and research applications requiring reliable viscosity data in the mid-range. The printed constant and DIN-type construction support straightforward calculation according to established standards. Supplied as a single piece with a net weight of 0,076 kg, it fits standard viscosity test setups used in analytical and industrial laboratories for routine and comparative measurements.

Questions about Ubbelohde viscometer 30-300mm²/s
What is this article?
Ubbelohde viscometer 30-300mm²/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.
