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 manufactured 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.
