Description
BS/U-tube reverse flow viscometer B is a precision glass capillary instrument for kinematic viscosity measurement in the range 2–10 mm²/s, with constant K = 0,01. Built to reverse-flow U-tube geometry, it is suited to both transparent and opaque liquids where standardised, reproducible viscosity values are essential. Every instrument is delivered with a factory calibration certificate and meets BS and ASTM D445-446 together with ISO 3104-3105, enabling direct use in regulated and routine laboratory methods. The lightweight unit has a net weight of 0,1 kg and is supplied as one piece from manufacturer Irmeco. Covering the mid-low viscosity window typical of many process oils, solvents and formulated products, this type-B viscometer supports quality control, research and method-development work. Calibration documentation and recognised standard compliance make it a dependable choice for laboratories performing kinematic viscosity determinations according to international test methods.

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.
