Dilution Viscometers

Calibrated CUDC (9721-M50) Series

For measurement of intrinsic viscosity 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 CUDU (9721-L50) Series

Similar to 9721-M50 series, but uncalibrated.

  • Minimum sample volume of 8 mL can be diluted to 40 mL. Require liquid bath depth of 305 mm (12 inches).
  • 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.
