Ubbelhode Dilution Viscometers

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

For convenient implementation of dilution series and determining concentration dependencies, e.g.
IV value measuring of polymers. Standard design with no thread for easy removal prior to external
cleaning. Can be connected with LAUDA VRM modules and dosing units. Recommended for automatic
measuring with LAUDA viscosity measuring systems.
• Fill volume: 15...75 ml
• Total length: approx. 290 mm
• Measurement accuracy: ±0.2 %

Ubbelhode Dilution 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.
Ubbelhode Dilution 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.
Ubbelhode Dilution 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.
Ubbelhode Dilution Viscometers
  • Customer-specific variants available on request
  • LUADA supplies special variants as desired by the customer, specifically for adaption to automatic measuring systems.
