Description
Ubbelohde viscometer 0,8-5 mm²/s, calibrated is a DIN-type capillary instrument for kinematic viscosity determination in the laboratory. It is built as size Nr. 0a with an internal diameter of 0,53 mm and constant K 0,005, and the constant is printed on the glass in accordance with ISO/DIN 3105, DIN 51502, BS 188 and KFT 60-100. The calibrated measuring range of 0,8-5 mm²/s suits low-viscosity Newtonian liquids where stable, reproducible efflux times are required under controlled temperature. The four-legged design supports secure immersion and handling in a thermostatic bath during serial measurements. Supplied as 1 pc with a net weight of 0,081 kg from manufacturer Witeg, the instrument is intended for routine analytical work, quality control and research applications that rely on standardized Ubbelohde geometry. Its DIN-compliant construction and factory calibration help laboratories compare results for oils, solvents and related fluids within the stated viscosity window, while the compact glass body remains practical for everyday bench use and bath setups.

Questions about Ubbelohde viscometer 0.8-5mm²/s calibrated
What is this article?
Ubbelohde viscometer 0.8-5mm²/s calibrated 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.
