Description
Ubbelohde viscometer 3-30 mm²/s is a DIN-type capillary instrument for kinematic viscosity measurement of transparent Newtonian liquids. Designated size Nr. Ic, it carries a printed constant in line with ISO/DIN 3105, DIN 51502, BS 188 and KFT 60-100. The four-limb glass body features an inner capillary diameter of 0,84 mm and constant K 0,03, spanning the measuring range 3–30 mm²/s. Supplied uncalibrated, the instrument is intended for laboratory use where efflux time and the printed constant yield kinematic viscosity under thermostatic control. Available as one piece from manufacturer Witeg, it supports quality control, R&D and educational workflows that rely on standardized capillary viscometry. The four-limb layout aids filling, thermal equilibration in a bath and clear meniscus reading. Suitable for oils, solvents and process media within the stated viscosity band, it offers a practical glassware solution for reproducible viscosity determinations according to common European and international methods.

Questions about Ubbelohde viscometer 3-30mm²/s
What is this article?
Ubbelohde viscometer 3-30mm²/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.
