Description
BS/IP/RF U-tube reverse flow viscometer 5 is a precision capillary instrument for kinematic viscosity measurement in the range 60–300 mm²/s, with viscometer constant K = 0,3. The reverse-flow U-tube design follows established BS/IP/RF geometry and is supplied with a factory calibration certificate. Conformity to BS/IP/RF as well as ASTM D445-446 and ISO 3104-3105 ensures results that are directly comparable with international laboratory methods. Offered as a single piece with a net weight of 0,1 kg, the instrument integrates readily into routine viscosity testing workflows that rely on calibrated glassware. This size-5 model from manufacturer Irmeco covers higher-viscosity samples whose kinematic viscosity lies between 60 and 300 mm²/s. When used with a temperature-controlled bath and accurate timing, it supports the classic capillary procedure referenced by the cited standards. The compact form and factory calibration make it a practical choice for quality-control and analytical laboratories performing standardised kinematic viscosity determinations.

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.
