BACKGROUND
Brook field viscometer is a type of volitional viscometer. It contains different size violating spindle which is immersed in the test material to be tested.1 The selection of the spindle is based upon the viscosity of the material. For liquid with low viscosity large size spindle are used while for high viscosity small size spindle are used.2,3
Aim: To determination of viscosity of prepared gel using brook field viscometer.
REQUIREMENTS
Chemical: Carbopole,
Gelatine,
Tragacanth,
Distilled Water.
Apparatus: Brook Field viscometer,
Beaker,
Mechanical stairer,
Glass rod.
PROCEDURE
Prepared the gel with different concentration of carbopole or gelatine. Setup the base level of the instrument using level indicator. The spindle was cleaned and attached to the instrument. Then the spindle was rotated in the gel until a constant reading displaced on the viscometer. Repeat the method for three times and find out the average value.
