Description
Ubbelohde viscometer 0,2-1 mm²/s, calibrated, is a DIN-type capillary glass instrument for precise kinematic viscosity measurement in the low-viscosity range. It bears a printed constant conforming to ISO/DIN 3105, DIN 51502 and BS 188, and is identified as size Nr. 0 with capillary constant K 0,001. The internal diameter is 0,36 mm, corresponding to the measuring range 0,2-1 mm²/s. Supplied calibrated and in a four-legged configuration, the design supports stable immersion and reproducible flow-time determinations under controlled temperature conditions. Pack size is one piece, with a net weight of 0,081 kg. This viscometer from manufacturer Witeg is suited to laboratory methods that rely on the referenced international and national standards for capillary viscometry. The four-legged DIN construction works with appropriate thermostatic baths and timing equipment typical of Ubbelohde workflows. Laboratories select this size when methods require the fine 0,36 mm bore and K 0,001 constant for the 0,2-1 mm²/s window. The printed constant and calibrated status support direct evaluation of kinematic viscosity from measured efflux times in routine analytical practice.

Questions about Ubbelohde viscometer 0.2-1mm²/s calibrated
What is this article?
Ubbelohde viscometer 0.2-1mm²/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.
