Description
Ubbelohde viscometer IV is a precision capillary instrument for kinematic viscosity determination in the measuring range 2000–10000 mm²/s, with viscometer constant K = 10. Designed for routine and quality-control applications involving Newtonian liquids, it enables standardised efflux-time measurements in analytical and industrial laboratories. Every unit is supplied with a factory calibration certificate, giving documented performance from the first determination. Construction and use follow DIN 51562 Part 1 and ISO 3105, ensuring compatibility with recognised viscosity testing protocols in petrochemical, lubricant, polymer and related sectors. The Ubbelohde suspended-level arrangement minimises the effect of sample volume on flow time and supports consistent, reproducible results run after run. Delivered as a single piece from manufacturer Irmeco, the instrument has a net weight of 0,1 kg and is easy to handle and store on the laboratory bench. Laboratories needing a calibrated capillary viscometer for the higher viscosity window will find this size IV model a reliable fit for existing DIN and ISO viscosity 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.
