Description
BS/U-tube reverse flow viscometer D is a precision capillary instrument for kinematic viscosity determination across the measuring range 20–100 mm²/s, with viscometer constant K = 0,1. The reverse-flow U-tube design enables accurate flow-time measurements on both transparent and opaque liquids under controlled temperature conditions. Each instrument is delivered with a factory calibration certificate and meets the requirements of BS and ASTM D445-446 together with ISO 3104-3105. Produced by Irmeco, this size-D capillary supports quality-control, formulation and research laboratories that need standardised kinematic viscosity data. With a net weight of 0,1 kg it integrates readily into conventional viscometer baths and support frames. Typical uses include evaluation of lubricating oils, process fluids, resins and other Newtonian samples where the reverse-flow geometry is specified. Supplied as one piece, the viscometer is prepared for immediate use in methods aligned with the referenced international standards.

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.
