Description
501 30 Ubbelohde Viscometer (DIN) is a calibrated glass capillary instrument designed for manual measurements of kinematic viscosity according to DIN requirements. It features capillary number III together with the viscometer constant K = 1, enabling accurate conversion of measured flow times into viscosity values for transparent Newtonian liquids. Supplied as a single piece with a net weight of 0,275 kg, the unit is intended for routine laboratory use where manual timing and controlled temperature baths are employed. The classic Ubbelohde design facilitates straightforward filling, observation of the meniscus, and cleaning between samples. This model from manufacturer SI Analytics - a Xylem brand supports reliable viscosity determination in quality-control, research and analytical workflows. Its calibrated performance ensures reproducible results when operated under standard conditions, making it a practical choice for laboratories that require precise manual viscosity data without automated systems. The robust construction and defined capillary geometry contribute to consistent day-to-day performance across repeated determinations.

Questions about 501 30, Ubbelohde viscometer (DIN), calibrated for manual measurements,
What is this article?
501 30, Ubbelohde viscometer (DIN), calibrated for manual measurements, 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.
