Description
511 13 Cannon-Fenske reverse-flow viscometer is a calibrated glass capillary instrument for manual viscosity measurements. This model is specified with capillary number 150 and viscometer constant K = 0,035, defining its measuring characteristics within the Cannon-Fenske Steigrohr series. The instrument is intended for laboratory determination of kinematic viscosity by manual timing of liquid flow through the calibrated capillary. It is supplied as one piece with a net weight of 0,275 kg and forms part of the 511 range of reverse-flow viscometers. Produced by SI Analytics - a Xylem brand, the 511 13 supports routine analytical and quality-control work where a size-150 capillary with the stated constant is required. Calibration for manual measurements ensures the constant K = 0,035 can be applied directly in viscosity calculations. The reverse-flow (Steigrohr) design is suited to transparent Newtonian liquids handled under controlled temperature conditions in the laboratory. Capillary number 150 together with K = 0,035 clearly identifies this size within the series, allowing selection according to the expected viscosity range of the sample. The unit is of German origin and is delivered ready for integration into existing manual viscometry workflows.

Questions about 511 13, Cannon-Fenske reverse flow viscometer, calibrated for manual
What is this article?
511 13, Cannon-Fenske reverse flow viscometer, calibrated for manual is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand 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.
