STANDARD OPERATING PROCEDURE

SUBJECT:                      OPERATION AND CALIBRATION OF BROOK FIELD VISCOMETER

DEPARTMENT           : QA SOP NO.                      : Page No                       : Effective Date             : Next Review                : SOP REVISION           :

1.0       OBJECTIVE:  

To provide guidelines for Operation & Calibration of Brookfield Viscometer.

2.0       POLICY: 

To determine the viscosity of viscous nature of the various Liquids, Creams and oils etc.

3.0       PROCEDURE:

3.1               Switch on the Viscometer.

3.2               Select the Spindle number or speed by adjusting the select knob on either side by adjusting the   

              round knob in the middle as per the Specifications.

3.3              Set the RPM as per the Specifications, by rotating the round knob in the middle of the Viscometer.  

             After setting the RPM & Spindle number, bring the select switch settings to normal position.

3.4               Fix the disc spindle or helipath spindle as required to viscometer, Immerse the spindle

into the sample contained in a 500ml beaker until the mark on the spindle rod adjust the

 height. If Helipath spindle is used it is fixed by helipath assembly to viscometer and the

 spindle will pierce through the cream. Incase of helipath spindle the spindle need not be

 immersed in the cream. Adjust the helipath spindle with the flat knob on the helipath

 stand.

3.5              Switch ON the button, the spindle starts rotating as per the set parameters.

3.6              Note the reading when the displayed value is stable.

3.7              Remove the spindle, clean and place in spindle box. Switch off the viscometer after use.

3.8              Enter the details in the log book.

  

3.9       CALIBRATION:

3.9.1    The calibration and regular maintenance of the viscometer is done by an external agency and is

            covered under Annual Maintenance contract.

3.9.2    The authorized service engineer of the external agency will check the performance of the

            viscometer and calibrate the same with traceable standards available with them.

3.9.3    The agency will provide a calibration certificate which is valid for a period of 6 months.

4.0       FREQUENCY               : As and when required.

5.0       RESPONSIBILITY      : Q.A Executive/chemist

6.0       REVIEW GUIDE          : Usage log book.
