Standard Operating Procedure for Using CO2 Incubator

1) Purpose

The purpose of this SOP is to describe the procedure for the proper operation and maintenance of the CO2 incubator in the pharmaceutical manufacturing of otic dosage forms to provide a controlled environment for cell culture and other biological processes.

2) Scope

This SOP applies to all personnel involved in the operation and maintenance of CO2 incubators in the pharmaceutical manufacturing facility.

3) Responsibilities

Operators: Responsible for correctly operating the CO2 incubator as per this SOP.
Quality Control (QC) Personnel: Responsible for monitoring the environmental conditions and ensuring they meet the required standards.
Maintenance Personnel: Responsible for maintaining the CO2 incubator in proper working condition.

4) Procedure

4.1 Pre-operation Checks
4.1.1 Inspection
4.1.1.1 Inspect the CO2 incubator for cleanliness and integrity before use.
4.1.1.2 Ensure that the CO2 gas supply is connected and operational.
4.1.1.3 Check that the control systems, sensors, and alarms are functional.

4.1.2 Preparation
4.1.2.1 Clean the interior surfaces of the incubator with a suitable disinfectant.
4.1.2.2 Verify that the water reservoir is filled with distilled water to maintain humidity.
4.1.2.3 Set the desired temperature and CO2 concentration as per the requirements.

4.2 Operation
4.2.1 Starting the CO2 Incubator
4.2.1.1 Turn on the CO2 incubator and allow it to reach the set temperature and CO2 levels.
4.2.1.2 Monitor the process parameters such as temperature, CO2 concentration, and humidity continuously to ensure they remain within the specified range.
4.2.1.3 Place the samples or cell cultures inside the incubator and close the door securely.

4.2.2 Safety Precautions
4.2.2.1 Wear appropriate personal protective equipment (PPE) when handling biological samples.
4.2.2.2 Avoid opening the incubator door frequently to maintain stable conditions.
