SOP for Operation Digital Automatic Tap Density Apparatus

OBJECTIVE

To provide a procedure for the Operation & Maintenance of Digital Automatic Tap Density Apparatus

SCOPE

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

RESPONSIBILITY

QA Executive

PROCEDURE

• Keep the instrument on a study level and near the electric connections
• Fix the connectors to the sockets as explained in the instruction Manual. Connect the main unit to 230m V 50 Hz Mains supply.
• Switch on the instrument, and 4 line LCD display becomes ON.
• Press the EDIT key and program the Test file for the sample explained in the instruction Manual.

• Pass the sample through a 1 mm screen.
• The cylinder must be absolutely dry from the inside.
• Weigh the desired quantity of the sample and fill it into the cylinder
• Carefully level the sample without compacting and read the volume.
• 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.
• Ensure that the S.S. Rod of the holder is clean. Otherwise, clean it properly.
• Apply a drop of oil if necessary.
• Press the START key and select the test file for the sample under test.
• Program operator Name, Batch No. and sample ID
• Enter the weight and Un-settled Volume of the sample
• 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
• Press START for initial tapping, after the final tapping, is over read the volume of the sample and enter it.
• The instrument calculates the percentage Difference in volume between two successive tappings if the difference is less than 2% then the instrument gives the message. TEST OVER.

• The instrument calculates Bulk Density, Tapped Density, Compressibility Index, and Hausner Ration of the sample.
• If the difference is more than 2% then the instrument continues the test further tapping till the Percentage difference in volume between two successive tappings is less than 2%
• After completion of testing, clean the measuring cylinder & instrument
• Follow the above steps as and when an instrument is used
