Description
516 30 Micro-Ostwald viscometer is a calibrated glass capillary instrument intended for manual viscosity measurements in the laboratory. It is specified with capillary no. III and constant K = 1, enabling calculation of kinematic viscosity from measured flow times under controlled conditions. The micro-Ostwald geometry is suited to classical capillary viscometry workflows where operators determine efflux times by hand and apply the instrument constant directly. Offered as 1 pc with a net weight of 0,275 kg and a gross weight of 0,275 kg, the unit fits routine analytical benches and teaching or quality-control setups that still rely on manual timing. This model comes from manufacturer SI Analytics - a Xylem brand and belongs to the Micro-Ostwald series used for comparative and absolute viscosity work. Capillary designation III together with the fixed constant K = 1 supports clear method documentation and straightforward transfer of results between runs. Laboratories performing polymer, solvent, or formulation checks can integrate the 516 30 into existing manual Ostwald protocols without altering calculation routines. The defined constant and capillary number make the instrument a practical choice wherever calibrated micro-scale capillary data are required.

What is this article?
516 30, Micro-Ostwald viscometer, calibrated for manual measurements, Capillary 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.
