Micro-Ostwald Viscometers

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

For small sample quantities and/or very short measurement times. Designed with no thread for easy
removal prior to external cleaning. Compatible with LAUDA VRM modules. Precise volume input
required. Especially recommended for heavy-foaming samples.
• Filling volume: 2 ml
• Total length: approx. 290 mm
• Measurement accuracy: ±0.5 %

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