Cannon Instrument Company - Ubbelohde Viscometers

Ubbelohde Viscometers

Calibrated UBC (9721-R50) Series

For measurement of kinematic viscosity of transparent Newtonian liquids by suspended level principle as described in ASTM D 445 and D 446, and ISO 3104 and 3105. Similar to Cannon-Ubbelohde but less rugged in design. Read more about the significance of expanded uncertainty. Provided with certificate of calibration and instruction sheet.

Uncalibrated UBU (9721-N50) Series

Similar to 9721-B50 series, but uncalibrated.

Ubbelohde Unity Factor Calibrated UBXC (9721-U50) Series

Similar to 9721-R50 series, but with constant within ± 0.2% of values listed in Table below. Provided with certificate of calibration and instruction sheet.

Holder is not supplied. For holders, see 9726-M82.
Minimum sample volume 11 mL. Require liquid bath depth of 241 mm (9.5 inches).

Viscometers with special constants are available by special order at additional cost.

Still need help choosing a viscometer? There are many reasons why one viscometer type is more appropriate or better suited than another. Because of these many reasons, we recommend you speak with one of our experienced staff members to assist you. You can however, use our viscometer selector to help point you in the right direction. The viscometer selector requires a target viscosity as input and outputs a list of viscometer types and sizes that are capable of measuring your target fluid.
