Description
Ubbelohde viscometer IIa is a precision capillary instrument for kinematic viscosity determination in the measuring range 100–500 mm²/s, with capillary constant K = 0,5. Built for standardised laboratory work, it supports reproducible flow-time measurements on Newtonian liquids such as oils, solvents and polymer solutions. The design follows DIN 51562 Part 1 and ISO 3105, so results align with widely accepted viscosity methods used in quality control and research. Each unit is delivered with a factory calibration certificate, giving documented traceability for routine analytical use. Manufactured by Irmeco, this glass Ubbelohde capillary integrates readily into thermostatic baths and existing viscosity measurement setups. Supplied as a single piece with a net weight of 0,1 kg, it is a compact choice for petrochemical, materials and general analytical laboratories that require a defined measuring range and certified calibration. The instrument enables consistent kinematic viscosity data according to established international procedures without unnecessary complexity in daily laboratory workflows.

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.
