To lay down the procedure for automatic basket mill operation. And Sop for micro-centrifuge or SOP of centrifuge

2.0 SCOPE

2.1  This procedure applies to Quality Control Department.

4.0 Procedure of Basket Mill Operation

4.1 Switch on the MCP 3 phase line and main switch.

4.2 Put the premix into the Desperate disperser.

4.3 Grind the premix for 4-5 hours. and check from the Hageman Gauge the particle size i.e. 2 microns.

4.4 If the particle size is not reached then further grind the pre-mix till the particle size becomes less than 2-micron check particle size from the Hageman Gauge after intervals of time.

4.5 Maintain a temperature of not more than 30° C. If the temperature increases by more than 30° C then start cooling by the circulation of cool water through the double-walled basket milling system.

4.6 After completing your pre-dispersion, the dissolver shaft can be replaced by the basket mill without the need for any tools.

4.7  Carefully draw pigment film on the drawdown paper with the help of DRAWDOWN BAR COATER.

4.8 Now take the dEand Strength reading in UV Visible Spectrophotometer Premier Color Scan Model No.-SS 5100A and compare the strength with each other.

4.9  Place the film on the drawdown paper in a folder, label the folder, and store it in a clean, dry place.

4.10 Now switch off the MCP 3 phase line and main switch.

Sop for microcentrifuge | SOP of centrifuge

To lay down the procedure for CLINICAL OR MICRO-CENTRIFUGE operation.

This procedure applies to Quality Control Department.

2.1 QC chemists to prepare and follow the SOP.

2.2 Head – QA & QC for implementation of SOP.

4.0  OPERATION PROCEDURE:

LOAD SAMPLES

4.1 Select the appropriate centrifuge based on the volume of the sample(s) and the desired speed and temperature.

4.2  Ensure that the centrifuge is located on a rigid, flat, level surface.

 4.3 Remove or lift the cover from the centrifuge. Insert sample(s) into the rotor making sure to place two samples opposite of each other to maintain balance.

4.4 If an odd number of samples need to be spun, make a counterbalance by filling an empty test tube or MICRO-CENTRIFUGE tube with an equal volume of water. 

4.5 Securely screw on or close the lid of the centrifuge.

CENTRIFUGE OPERATION

4.6 Set the desired speed, time, and temperature (if applicable) on the centrifuge.

4.7 Press the “Start” button and wait for the instrument to ramp up to the desired speed.

Note: It is normal to see a small vibration in the instrument as the speed increases, but any large vibration in the instrument or irregular noise may indicate that something has gone wrong with the run.  Press the “Stop” button and make sure that the tubes are balanced properly.

4.8  When the run has completed and the rotor has come to a complete stop, unscrew the rotor lid and carefully remove the samples to prevent re-suspension of the sediments
