Description
538 21 Micro-Ubbelohde viscometer (DIN), not calibrated, capillary no. IIa is a precision laboratory instrument designed for kinematic viscosity measurements of small sample volumes using the established Ubbelohde suspended-level principle. With capillary number IIa and constant K = 0,5, it is intended for dilute solutions and low- to medium-viscosity Newtonian liquids in accordance with DIN requirements. The uncalibrated configuration gives users full flexibility to calibrate the capillary against reference materials according to their own quality-assurance protocols. Offered as one piece with a net weight of 0,275 kg, the micro design minimises both sample volume and solvent consumption. Manufactured by SI Analytics - a Xylem brand, this viscometer is widely applied in polymer chemistry, pharmaceutical analysis and materials research where economical yet reliable viscosity data are required. It integrates readily into temperature-controlled baths and supports routine flow-time determination for transparent fluids in research, development and quality-control laboratories.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 538 21, Micro-Ubbelohde viscometer (DIN), not calibrated, Capillary No. IIc,
What is this article?
538 21, Micro-Ubbelohde viscometer (DIN), not calibrated, Capillary No. IIc, 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.
