Description
545 11 Ubbelohde viscometer (ASTM), calibrated for automatic measurements, is a precision capillary instrument for kinematic viscosity determination in laboratory settings. It is fitted with capillary no. 1B and carries the constant K = 0,05. An integrated filling and cleaning tube supports convenient sample introduction and subsequent rinsing of the measuring path. Designed to ASTM requirements, the glass viscometer is calibrated specifically for use with automatic measuring systems. Supplied as 1 pc with a net weight of 0,28 kg, the unit originates from Germany. The 545 11 model from manufacturer SI Analytics - a Xylem brand provides a classic Ubbelohde measuring geometry suited to routine analytical viscosity workflows. Factory calibration for automatic operation supports consistent flow-time determination through the capillary under controlled conditions. The filling and cleaning tube forms part of the assembly, enabling efficient preparation between successive samples. This configuration is appropriate where standardised, calibrated Ubbelohde viscometers are required for laboratory viscosity work. The stated capillary constant allows calculation of kinematic viscosity once flow times are recorded on compatible automated platforms.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
545 11, Ubbelohde viscometer (ASTM), calibrated for automatic measurements, with 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.
