Vacuum Viscometers - Senze-Instruments Benelux

In most glass capillary  viscometers, the  samples flow  under gravity.

When liquids are too viscous to flow  readily under gravity, vacuum viscometers may be  used to measure viscosity (in mPa•s or cP).

In these instruments a vacuum is applied to one end of the  viscometer to pull the  liquid through the  capillary  into the  timing bulb(s).

CANNON offers several  types of vacuum viscometers, including the  Cannon-Manning Vacuum , the  Asphalt Institute Vacuum, and the  Modified Koppers Vacuum.

Like the  Cannon-Fenske Opaque viscometer, these are all “reverse  flow” viscometers.

Vacuum viscometers require a vacuum that is very  accurately controlled. The CANNON

DVR-1000 or DVR-1500 Digital Vacuum Regulator is an ideal instrument for maintaining constant vacuum.

Calibrated CMVC Series

For measurement of viscosity of highly viscous materials such as asphalt  cement at 60°C (140°F) according to ASTM D 2171.

Applicable to materials with viscosity range of 0.036 to 80 000 poise.

Vacuum of 300 mm Hg is applied to small arm with timing bulbs; two bulbs are incorporated to extend viscosity range of viscometer.

Same as 9724-H50 series, but with permanently attached round metal holder, for hole 51 mm in diameter.

Similar to 9724-H50 series, but with graduated capillary  instead of two timing bulbs.

Calibrated AIVC-RO Series Same as 9724-R50 series, but with permanently attached round metal holder,

for hole 51 mm in diameter.

For measurement of viscosity of asphalts  at 60°C in accordance with ASTM Standard D2171.

Applicable to materials with viscosity range of 42 to 200 000 poise.

Two piece design, with sample reservoir  and calibrated capillary. Vacuum of 300 mm Hg must be  applied to top  of capillary tube.
