Description
509 05 Ostwald viscometer is a classic glass capillary instrument for determining the kinematic viscosity of Newtonian liquids by measuring efflux time under controlled conditions. This non-calibrated model carries a capillary constant K of 0,03 and is intended for laboratories that establish or verify the constant themselves before routine use. Supplied as 1 pc with a net weight of 0,275 kg, the unit suits immersion-style or standard Ostwald flow measurements on transparent, low- to medium-viscosity samples. The instrument is produced by SI Analytics - a Xylem brand and belongs to the established 509 series used in analytical chemistry, quality control and teaching laboratories. Its simple U-tube capillary geometry allows reliable timing of liquid flow once temperature and filling conditions are standardised. Typical applications include solvent characterisation, dilute polymer solutions and comparative viscosity checks where an uncalibrated capillary of known nominal constant is preferred. Originating from Germany, the 509 05 provides a durable, easy-to-clean glassware solution for everyday viscosity work without pre-assigned calibration certificates.

Questions about 509 05, Ostwald viscometer, not calibrated, constant K = 0.03
What is this article?
509 05, Ostwald viscometer, not calibrated, constant K = 0.03 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.
