Standard Operating Procedure for Using Incubator

1) Purpose

The purpose of this SOP is to describe the procedure for the proper operation and maintenance of the incubator used in the manufacturing of otic dosage forms to ensure optimal conditions for microbial growth or product stability testing.

2) Scope

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

3) Responsibilities

Operators: Responsible for correctly operating the incubator as per this SOP.
Quality Control (QC) Personnel: Responsible for monitoring the incubation process and recording observations.
Maintenance Personnel: Responsible for maintaining the incubator in proper working condition.
