Description
Ubbelohde viscometer 10-100 mm²/s, calibrated is a DIN-type capillary instrument for kinematic viscosity determination in the measuring range 10-100 mm²/s. It is designated capillary Nr. II, with an internal diameter of 1,13 mm and a printed constant K of 0,1. The viscometer follows ISO/DIN 3105, DIN 51502, BS 188 and KFT 60-100, and the constant is printed on the body for direct evaluation of measured times. Supplied calibrated in a four-limb configuration, this Ubbelohde viscometer from manufacturer Witeg supports laboratory work on liquids whose viscosity lies within the stated window. Defined capillary geometry, printed constant and calibration status together enable reproducible kinematic viscosity results according to the referenced norms. Pack size is 1 pc; net weight is 0,081 kg. Analytical and quality-control laboratories use calibrated Ubbelohde capillaries of this type when standardised viscosity data are required. The DIN-type four-limb design with Nr. II parameters matches common practice for the 10-100 mm²/s interval, giving a ready-to-use instrument whose constant and internal diameter are clearly indicated for routine viscosity calculations.

Questions about Ubbelohde viscometer 10-100mm²/s calibrated
What is this article?
Ubbelohde viscometer 10-100mm²/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.
