SUBJECT :                                             LAB EQUIPMENT DIGITAL AUTOMATIC TAP DENSITY APPARATUS

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

           

1.0        OBJECTIVE:

           

             To provide guidelines for Operation & Maintenance of Digital Automatic Tap Density

            Apparatus

2.0        SCOPE :

To establish a procedure for an operation of Digital Automatic Tap Density Apparatus

3.0        PROCEDURE:

3.1       Keep the instrument on a study level and near to the electric connections

3.2       Fix the connectors to the sockets as explained in the instruction Manual. Connect the main

           unit to   230m V 50 Hz Mains supply.

3.3       Switch on the instrument, 4 line LCD display becomes ON.

3.3        Press EDIT key and program the Test file for the sample explained in the instruction 

             Manual.

 3.4      Pass the sample through 1 mm screen.

3.5       The cylinder must be absolutely dry from inside.

3.6       Weigh the desire quantity of the sample and fill it into the cylinder

3.7       Carefully level the sample without compacting and read the volume.

3.8       Place the cylinder in its holder and mount it on the USP-I or USP –II port as per the test                   

             selected. Cover the unused port with the PVC Stopper supplied with the instrument.

3.9        Ensure that the S.S. Rod of the holder is clean. Otherwise clean it properly.

3.10      Apply a drop of oil if necessary.

3.11     Press START key and select the test file for the sample under test.

3.12     Program operator Name, Batch No. and sample ID

3.13     Enter the weight and Un-settled Volume of the sample

3.14     Press start for initial tapping and observe that the cylinder is tapped

            After initial tapping is over, read the volume of the sample and enter it

3.15    Press START for initial tapping, after final tapping is over read the volume of the sample and enter   it.

3.16   The instrument calculates the percentage Difference in volume between two successive tapping if the difference is less than 2% then the instrument give the message. TEST OVER,

3.17   The instrument calculates Bulk Density, Tapped Density, Compressibility Index and Hausner Ration    of the sample.

3.18    If the difference is more than 2% then the instrument continues the test further tapping till the                     Percentage difference in volume between two successive tapping is less than 2%

3.19    After completion of testing, clean the measuring cylinder & instrument

3.20    Follow the above steps as and when instrument is used

4.0      FREQUENCY: As and when required.
