  • Cleaning Glass Capillary Viscometers
    Clean viscometers are essential for precise and accurate measurements. Because CANNON receives a significant number of requests for advice concerning proper cleaning methods, we offer the following instructions as a guide to cleaning most glass capillary viscometers.
  • Calculation of Viscometer Constants for Cannon-Fenske Routine and Cannon-Fenske Opaque Viscometer
    Certain modified Ostwald-type viscometers for transparent liquids (like the Cannon-Fenske. Routine and the Cannon-Manning Semi-Micro) and reverse-flow viscometers for opaque and. transparent liquids (like the Cannon-Fenske Opaque) are always filled with a precise volume. of test sample. Because
  • SPECTROVISC Q3000 SERIES VISCOMETER - A PORTABLE KINEMATIC OIL ANALYSIS SOLUTION FOR FIELD-BASED USERS
    This paper describes how using the handheld, solvent-free SpectroVisc Q3000 Series device in the field provides immediate and accurate kinematic viscosity measurements, even when compared to traditional laboratory viscometers. The SpectroVisc Q3000 Series uses new solvent-free technology
  • High Speed, Small Sample Rheometric Screening Using the Cambridge Viscosity Viscometer (.pdf)
    Characterizing a fluid's rheology rapidly while using only a small amount of fluid (<2mL) is highly advantageous in many applications. Unfortunately, this has not historically been possible in most instances. In fact, such characterizations require significant time, fluid, and technician skill.
  • Viscosity Measurment Application Notes
    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque
  • Does D445 Require Use of a Full Length Capillary Tube?
    Labs are sometimes under the mistaken impression that modern, automated viscometers that use shorter capillary tubes are out of compliance with ASTM D445/ASTM D446.
  • Ask the Expert: Measuring the Viscosity of an Oil
    using kinematic viscometers and reported in centistokes (cSt). Viscosity can also be measured using absolute (dynamic) viscosity techniques and reported in centipoise. Absolute techniques typically use rotational viscometers, whereas kinematic techniques will commonly use flow viscometers dependent
  • Application Note: Mouthwash
    We used a Brookfield LVDV-III Ultra Rheometer with Rheocalc v3.1 software for automated instrument control and data acquisition. (Note: any standard Brookfield Viscometer or Rheometer would apply.)
