Cannon-Ubbelohde
Semi-Micro Viscometers

Calibrated CUSMC (9721-H50) Series

For measuring kinematic viscosity of small samples of transparent Newtonian liquids according to ASTM D 445 and ISO 3104. Specifications conform to ASTM D 446 and ISO 3105. Viscometer constant is same at all temperatures. Read more about the significance of expanded uncertainty.

Provided with certificate of calibration and instruction sheet.


Uncalibrated CUSMU (9721-G50) Series

Similar to 9721-H50 series, but uncalibrated.

  • Minimum sample volume approximately 1.0 mL. Sizes 400 through 600 may require larger sample volume. Initial sample can be diluted to as much as 20 mL for intrinsic viscosity determinations. Require liquid bath depth of 240 mm (9.5 inches).
  • Size 25 has approximate constant 0.002 cSt/s and a range of 0.4 to 2 cSt.
  • Holder is not supplied. For holders, see 9726-M70, 9726-M73, 9726-M76.
  • Viscometers with special constants are available by special order at additional cost.
