Description
Ubbelohde viscometer 3B is a capillary instrument for kinematic viscosity determination in the measuring range 1000–5000 mm²/s, with capillary constant K = 5.0. It is delivered with a factory calibration certificate and meets ASTM D445-446, ASTM D2515 and ISO 3104-3105, the established standards for laboratory kinematic viscosity methods. The defined constant supports calculation of kinematic viscosity from observed efflux times in line with those procedures. Supplied as 1 pc with a net weight of 0,1 kg, the unit from manufacturer Irmeco is intended for analytical and quality-control laboratories that require a size 3B Ubbelohde capillary. Country of origin is Spain. The instrument addresses the upper mid-range viscosity window linked to this capillary size and is suited to controlled laboratory measurement within 1000–5000 mm²/s. This factory-calibrated Ubbelohde viscometer offers a practical solution when works calibration documentation and compliance with the referenced ASTM and ISO standards are specified for kinematic viscosity testing.
This article is part of Viscometers, in Density & viscosity measurement.

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.
