Description
Ubbelohde viscometer 1000-10000 mm²/s is a DIN-type capillary glass instrument for kinematic viscosity determination in the laboratory. It carries a printed constant in accordance with ISO/DIN 3105, DIN 51502 and BS 188, and is designated size Nr. IV with capillary constant K 10. The internal diameter is 3,60 mm, matching the measuring range 1000-10000 mm²/s for higher-viscosity samples. This uncalibrated, four-legged design supports stable immersion during timed flow measurements under controlled bath conditions. Supplied as one piece with a net weight of 0,081 kg, the viscometer fits routine quality-control and research workflows that follow established capillary viscometry practice. The instrument from manufacturer Witeg is intended for use with suitable thermostatic equipment and timing methods typical of Ubbelohde procedures. Four-legged construction aids positioning in the bath while the printed constant enables calculation of kinematic viscosity from measured efflux times once laboratory calibration status and temperature conditions are defined. Laboratories can integrate this size into an existing Ubbelohde series whenever the K 10 constant and 3,60 mm bore are required for the 1000-10000 mm²/s window.

Questions about Ubbelohde viscometer 1000-10000mm²/s
What is this article?
Ubbelohde viscometer 1000-10000mm²/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.
