Use with K23320 and K23350 rectangular metal holders or K23382 and K23351 round plastic holders. Requires a sample volume of approximately 11mL.
Suspended-level type viscometer for kinematic viscosities of transparent liquids of up to 100,000cSt. Use with K23310 and K23350 rectangular metal holders or K23381 and K23351 round plastic holders.
Can be used for kinematic viscosities of asphalts by ASTM D2170 method. Allows timing of samples whose thin films are opaque and are thus not suitable for modified Ostwald and suspended-level type viscometers. Reverse-flow viscometer for measurement of transparent and dark liquids having kinematic viscosities of up to 100,000cSt. Please refer to page 13 for information about the Koehler Vacuum Regulator.įor kinematic viscosity of transparent liquids up to 100,000cSt. These vacuum viscometers require an accurately controlled vacuum regulator for proper measurement. Koehler offers the Cannon®-Manning Vacuum, the Asphalt Institute Vacuum, and the Modified Koppers Vacuum reverse flow viscometer tubes. A vacuum is applied to one end of the viscometer to pull the liquid through the capillary into the timing bulb. When liquids are too viscous to flow readily under gravity, vacuum viscometers may be used to measure viscosity. In most glass capillary viscometers, the samples flow under gravity. Dilute polymer solutions frequently appear to exhibit changes in kinematic viscosity when the shear rate is changed. The Cannon®-Ubbelohde Dilution viscometer has an extra large reservoir which allows polymer solutions to be diluted several times and measures viscosities at four different shear rates. Several semi-micro viscometers have been designed which require one milliliter or less of liquid, which include the Cannon®-Manning Semi-Micro, Cannon®-Manning Semi-Micro Extra Low Charge, and Cannon®-Ubbelohde Semi-Micro viscometers.Įstimates of the molecular size and shape of large polymers molecules can be obtained from kinematic viscosity measurements of dilute solutions. By contrast, other viscometer types commonly used to measure transparent liquids allow the sample to be repeatedly drawn up into the capillary, permitting duplicate measurements. These viscometers wet the timing section of the viscometer capillary only during the actual measurement and must be cleaned, dried and refilled before a repeat measurement can be made. The Cannon®-Fenske Opaque, Cross Arm, and BS/IP/RF U-Tube viscometers have been designed for testing opaque liquids. Other suspended level viscometers in this catalog include the BS/IP/SL, BP/IP/SL(S), and BP/IP/MSL viscometers. Unlike the Cannon®-Fenske Routine viscometer, suspended level viscometers maintain the same viscometer constant at all temperatures, which is advantageous when samples are to be measured at different temperatures. The Ubbelohde viscometer and other suspended-level viscometers are used to measure transparent liquids.
Other viscometers for transparent samples in this catalog include the Cross Arm and BS/U-Tube viscometers. The Cannon®-Fenske Routine viscometer is a rugged and inexpensive viscometer that works well if the sample is transparent or translucent. Please refer to the following brief descriptions for determining which viscometer is best suited for your particular application. Each viscometer is supplied with a calibration certificate, and holders should be ordered separately. All types of viscometers conform to ASTM D446 and related standard specifications for glass capillary kinematic viscometers.
