Description
511 30 Cannon-Fenske reverse-flow viscometer is a precision glass capillary instrument calibrated specifically for manual kinematic viscosity measurements. It incorporates capillary number 400 together with the instrument constant K = 1,2, enabling reliable timing of liquid flow under controlled temperature conditions in laboratory immersion baths. The reverse-flow (Steigrohr) geometry is particularly suited to transparent Newtonian fluids and supports standard manual protocols used in quality-control and research environments. Supplied as one piece with a net weight of 0,275 kg, the viscometer is manufactured by SI Analytics - a Xylem brand and is intended for routine determination of fluid viscosity in chemistry, petrochemistry, polymer and materials-testing laboratories. Operators fill the instrument, allow thermal equilibration, and measure efflux time through the calibrated capillary; the known constant then converts the observed time into kinematic viscosity. Its robust construction withstands repeated thermal cycling and cleaning cycles typical of daily laboratory use. The design ensures clear meniscus visibility and reproducible results when employed according to established manual viscometry procedures, making it a practical choice for laboratories that rely on classical capillary methods rather than automated systems.

Questions about 511 30, Cannon-Fenske reverse flow viscometer, calibrated for manual
What is this article?
511 30, 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.
