RESPONSIBILITY

Q.C. Chemist / Q.C Executive.

ACCOUNTABILITY

Manager Q.C.

PROCEDURE

Operation

• The apparatus consists of the following switches.

• Connect the instrument to a 230 V supply.

• Switch ON the instrument.
• Weigh at least 10 g of sample and transfer it to a 50 ml (or 25 ml which is suitable) measuring cylinder. Put a stopper on it.
• Fix the measuring cylinder on the Bulk density stand.
• Set the apparatus to the required strokes by adjusting switches.
• Put on the STRT switch.

• The apparatus starts working and the stroke rate is displayed on the screen.
• After the completion of the specified stroke. The apparatus will go OFF automatically with a buzzer.
• For repeating the analysis. Press STRT.
• Switch off the MAIN after the analysis.
• Calculate the bulk density of the sample by measuring the volume of the sample on the measuring cylinder, occupied after setting it specified strokes.

Calibration

• Put ON the mains.
• Set the apparatus for 50 strokes by adjusting the push button.
• Put STRT on the switch.
• Counter the number of strokes.
• Change the setting to the following number of strokes and check the actual strokes.

• Report the results in the format given in Annexure I.
• If the calibration is not proper then report to the department head for appropriate action.

FREQUENCY

Monthly.
