VISCOMETER CANNON

Product Description

VISCOMETER CANNON

CANNON Instrument Company® has been making glass capillary viscometers since 1938. We offer a variety of glass capillary viscometers because no single viscometer is ideally suited to every application. Use of high quality instruments ensures test reliability and accuracy. All CANNON glass capillary viscometers are traceable to a NIST calibration and manufactred in our ISO 9001-registered, A2LA-accredited laboratory. Our experienced staff is happy to assist you with viscometer selection. We offer the following viscometer types:

 

Transparent		For transparent/translucent liquids
Suspended Level		For transparent/translucent liquids. Ideal for testing at multiple temperatures because they have the same viscometer constant at all temperatures.
Dilution		For dilution of polymer solutions to provide an estimate of the molecular size and shape.
Reverse Flow		For transparent and opaque liquids. Must be cleaned, dried and refilled between repeat determinations.
Vacuum		A special type of reverse-flow viscometer for highly viscous samples (transparent or opaque). Accurately controlled vacuum is required to pull the liquid through the viscometer.

1/ CANNON-Fenske Routine Viscometer

The Cannon-Fenske Routine Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is 7 mL. Minimum bath depth is 203 mm (8 in). Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.

† Viscosity ranges in mm²/s represent flow times of 250 to 1000 seconds for size 25
and 200 to 1000 seconds for all other sizes

2/ Fenske Opaque Viscometer 

The Cannon-Fenske Opaque Viscometer measures kinematic viscosity of transparent and opaque Newtonian liquids according to ASTM D445, ISO 3104 and ASTM D2170. Minimum sample volume is 12 mL. Minimum bath depth is 230 mm (9 in). Special constant viscometers are available at additional cost. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet.
