Description
Ubbelohde viscometer IVa is a precision capillary instrument for kinematic viscosity determination in the measuring range from 10000 to 50000 mm²/s, with a capillary constant K of 50. It is supplied with a factory calibration certificate, supporting documented measurement traceability for routine and comparative laboratory work. The design follows DIN 51562 Part 1 and ISO 3105, the established reference standards for glass capillary viscometers used in quality control and research. Ubbelohde geometry enables suspended-level operation, which helps reduce hydrostatic head effects during efflux timing and supports reproducible results across higher-viscosity fluids. With a net weight of 0,1 kg, the instrument is compact and straightforward to place in temperature-controlled baths commonly employed for viscosity testing. Available from manufacturer Irmeco, this model suits laboratories that characterise oils, resins, polymers and other process liquids where elevated kinematic viscosities must be measured under controlled conditions. Conformance to the cited DIN and ISO methods assists method consistency between sites and operators. Pack size is one piece, ready for direct integration into existing viscosity workflows without additional configuration steps.

Questions about Viscometer
What is this article?
Viscometer is the article on this page. Luminix Health distributes Irmeco 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.
