Description
509 06 Ostwald viscometer is a glass capillary device designed for kinematic viscosity determination of Newtonian fluids via timed flow through a defined capillary. This non-calibrated version features a capillary constant K of 0,07, making it suitable for sample ranges that require a somewhat higher constant than the lower-K models in the same series. Delivered as 1 pc and weighing 0,275 kg net, the instrument supports standard Ostwald or immersion measurement protocols once the laboratory has established the working constant. Manufactured by SI Analytics - a Xylem brand, the 509 06 is part of a well-known line of laboratory viscometers used in chemical, pharmaceutical and materials laboratories. The straightforward U-tube design facilitates cleaning and repeated use with transparent liquids under temperature-controlled conditions. Typical applications include quality-control checks, solvent screening and educational demonstrations of capillary viscometry. Produced in Germany, this uncalibrated Ostwald viscometer offers a practical glassware option for laboratories that prefer to perform their own calibration or comparative measurements.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 509 06, Ostwald viscometer, not calibrated, constant K = 0.07
What is this article?
509 06, Ostwald viscometer, not calibrated, constant K = 0.07 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.
