Glass capillary viscometers

Viscosity measuring with Ubbelohde, Cannon-Fenske and Micro-Ostwald capillary viscometers

Glass capillary viscometers are available in various designs, which differ with respect to application area, accuracy and operation. As of now, they can be supplied by LAUDA in the Ubbelohde, Cannon-Fenske, Micro-Ostwald and special designs. For high-precision, automatic measuring, the Ubbelohde version with the suspended level is preferred, among other reasons because the flow time is independent of the precise sample volume. To keep the measuring times within the optimum range between approx. 60 and 600 s, different capillary diameters are supplied to cover the complete viscosity range. The procedure, particularly with automatic LAUDA measuring technology and precise temperature control using LAUDA clear-view thermostats, is unrivaled in terms of accuracy for measuring liquids with nearly Newtonian (ideal) flow properties.

Glass capillary viscometers
  • Ring marks with no detection disturbances
  • Precise, positioned, NIR permeable ring marks with exactly 40 mm clearance. The capillary constant is valid for stopwatch and automatic measuring systems.
Glass capillary viscometers
  • Corrosion resistant labelling
  • There is no risk of abrasion or etching off of the labeling even with the use of strong acids and aggressive solvents used as samples or cleaning agents.
Glass capillary viscometers
  • Ubbelohde for dilution series with calibration certificate and filter fit
  • Absolute measuring now also possible with calibrated dilution viscometers. The integrated frit ensures filtration when the sample dissolves in the viscometer.
  • Complete application from one supplier
  • LAUDA supplies all components for the viscosity application - clear-view thermostats, automatic viscosity measuring systems and glass capillary viscometers.
Glass capillary viscometers
  • Customer-specific variants available on request
  • LUADA supplies special variants as desired by the customer, specifically for adaption to automatic measuring systems.
