This Document describes (Standard Operating procedure) Sop for Operation and Calibration of Vacuum Pump for filtration.

Sop for Operation and Calibration of Vacuum Pump for filtration

I. Purpose & Scope:

• The Purpose of this SOP is to lay down the procedure to lay down a procedure for Operation, Cleaning & Calibration of Vacuum Pump for filtration.
• This procedure is applicable for Operation, cleaning & Calibration of Vacuum Pump for filtration used in Quality Control Department

II. Responsibilities:

•  All  Quality Control personnel’s shall be responsible to follow and implement this SOP.

III : Introduction and Procedural Part :

General Cleaning :

• Clean the instrument with a clean dry cloth every day. Occasionally wet cloth dipped in dilute soap solution may be used.
• Precautions has to be taken to clean the instrument immediately with dry cloth to remove the moisture.

Basic Operation of Vacuum pump for filtration :

For Applying Vacuum to the filtration:

• Select the vacuum operation mode by opening the vacuum regulator valve. (Keep pressure regulator valve closed throughout the operation).
• During vacuum filtration, use a vacuum-flask through water trap to prevent excessive amount of liquids or mist from entering the pump.
• Prepare the filter holder ready for filtration. Do not connect the tubing to the pump [Do not turn on the pump with all tubing and equipment fully connected.  The pump may not function properly if turned on with an initial load].
• Plug the power cord into a grounded electrical source 230V. Switch on the main switch of power supply.
• Switch on the pump.
• Load the filter holder and connect the tubing from the filter holder through water trap to the pump.
• After completion of work run the pump for about 30 seconds freely and turn off the pump.

For Applying Vacuum to the filtration:

• Prepare equipment ready for vacuum operation and follow the procedure as below.
• Plug the power cord into a grounded electrical source 230V. Switch on the main switch of power supply.
• Switch on the pump.
• Connect the tubing and adjust the required vacuum with the help of vacuum regulator.
• After completion of work, run the pump for about 30 sec. freely and turn off the pump.

Calibration :

Calibration Frequency:

• Calibration done by external Agency once in year.
• Handle the out of calibration results as respective SOP.
