CANNON Ubbelohde Viscometer
RM 0.00
Description
STM D445, ISO 3104
CANNON Ubbelohde Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is 11 mL. Minimum bath depth is 241 mm (9.5 in). Unity factor series has a constant within +/- 0.2% of the values listed. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. CANNON Ubbelohde Viscometer Holders are sold separately.
Use of high quality instruments ensures test reliability and accuracy, and all CANNON glass capillary viscometers are traceable to a NIST calibration and manufactured in our ISO 9001-registered, A2LA-accredited laboratory. CANNON Instrument Company has been making glass capillary viscometers since 1938 and because no single viscometer is ideally suited to every application, we offer a wide variety of glass capillary viscometers. Our experienced staff is happy to assist you with viscometer selection. Viscometer options include:
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. |
