Calibration
of Apparatus suitability:
6.5.1
Calibration
for Disintegrating Type:
6.5.1.1
Prepare
standard solution of Prednisone:

Prepare the
standard solution by dissolving the 25mg of prednisone to 50.0ml of purified
water.
6.5.1.1.2
Further dilute
5.0ml from this solution to 50.0ml with purified water.
6.5.1.1.3
Again make
dilution of this 5.0ml to 25.0ml with purified water.
6.5.1.1.4
And take
absorbance at 242nm against the purified water.
6.5.1.1.5
NOTE:
If
the standard is not dissolve first add not more than 2.5ml of alcohol.
6.5.1.2
Dissolution
calibration by using Prednisone tablet:
6.5.1.2.1
Ensure that mains
of instrument and supply are “ON”.
6.5.1.2.2
Set the time
program for 30 min, temperature 37oC±0.5oC and for 50
RPM.
6.5.1.2.3
Fit the required apparatus
paddle.
6.5.1.2.4
Place 900.0ml of
deaerated water. De-aerate the purified water according to SOP for de-aeration
of dissolution media.
6.5.1.2.5
After achieving
the temperature place one tablet in each bowl and start the time program.
6.5.1.2.6
After completion
of time program withdraw the sample solution from each bowl and filter through
the filter paper in individual tubes. Discard first 50.0ml filtrate, take 5.0ml
of filtrate and dilute with purified water to 25.0ml and take the absorbance at
242nm against the purified water.
6.5.2
Calculate the
content of prednisone.
6.5.3
Also carry out
above procedure for 100 RPM.
6.5.4
Enter the data in
the calibration record.
6.5.5
Also carry out
above procedure by changing the basket apparatus for 100 RPM and enter the data
in calibration log.
6.5.6
Precautions:
6.5.6.1
If the calibration
is not found within the specified limits immediately inform to QC head.
6.5.6.2

should be fall within the limit as given in the calibration log.
6.6.2
Paddle:
6.6.2.1
Make identity of
each paddle which is in use and make the inventory.
6.6.2.2
Check the physical
parameters for the each paddle like appearance, height, shaft diameter, blade
upper chord, lower chord, height, radius (disk), thickness, and distance from
bottom, distance shaft axis and vertical axis of vessel.
6.6.2.3
All parameters
should be fall within the limit as given in the calibration log.
6.7
Checking
of wobbling, rotations & distance parameters for the apparatus:
6.7.1
Wobbling:
6.7.1.1
Fix the paddle/
basket apparatus to the instrument, lower the apparatus.
6.7.1.2
Fix the wobbling
meter on the top of the bowl.
6.7.1.3
The needle of
wobbling meter should touch to the surface of the apparatus.
6.7.1.4
Measure the
wobbling on the meter.
6.7.2
Rotations:
6.7.2.1
Fix the paddle/
basket apparatus to the instrument.
6.7.2.2
Set the RPM
50/100.
6.7.2.3
The needle of
tachometer should touch to the surface of the apparatus.
6.7.2.4
Press the “Start”
key of tachometer to start.
6.7.2.5
Fix the tachometer
with apparatus.
6.7.2.6
Start the
rotation.
6.7.2.7
The tachometer
will show result on display.
6.7.3
Distance
from the apparatus:
6.7.3.1
Fix the paddle/
basket apparatus to the instrument, lower the apparatus.
6.7.3.2
Insert the vernier
calipers between the bottom of the apparatus and the bottom of the bowl.
6.7.3.3
Measure the
reading on the display.
