Description
The 518 10 Micro-Ostwald viscometer is an uncalibrated precision capillary instrument fitted with capillary number I and constant K = 0,01. This micro-scale Ostwald-type viscometer is intended for kinematic viscosity work that requires subsequent individual calibration or comparative measurements with small sample volumes. Supplied as 1 pc with a net weight of 0,275 kg and matching gross weight of 0,275 kg, it suits laboratory environments where users establish their own calibration constants. Produced in Germany by manufacturer SI Analytics - a Xylem brand, the unit provides a defined capillary geometry suitable for flow-time determinations of transparent liquids. The uncalibrated configuration allows flexible adaptation to specific automatic or manual measurement setups common in analytical laboratories. It belongs to the viscometer category and is appropriate for research, method-development and industrial settings that need a micro-Ostwald capillary of known nominal constant. The compact design facilitates efficient handling while preserving the geometric precision required for reliable capillary flow analysis under controlled laboratory conditions.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
518 10, Micro-Ostwald viscometer, not calibrated, Capillary No. I, Constant K = 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.
