Validation Protocol for Hold Time Study of Sterilized Glassware and Accessories

Learn how to validate the sterilized glassware and other analysis accessories to hold for a period of 5 days under LAF.

1.0 OBJECTIVE

       The objective of this protocol is to provide documented evidence through the scientific data to establish and verify the microbial presence on sterilized glassware and accessories upon holding up to the specified time after sterilization by using the microbial detection method.

2.0 SCOPE

       The scope of this protocol is to evaluate the hold time of sterilized glassware and accessories after sterilization in an autoclave.

3.0 Reference Document

4.0 Responsibility

4.1  Quality Assurance
       Review and approval of protocol
4.2  Quality Control
       Preparation, review and execution of protocol

5.0 ACCOUNTABILITY

       Head QA & QC

6.0 Procedure

6.1 Pre-Requisite
Environmental conditions should be maintained within the established limit.
6.2 Procedure For Hold Time Study
6.2.1  Perform the sterilization of the following material Screw capped bottles, Miliflex funnels, SS frits and tips as per the SOP for sterilization.
6.2.2  Store the sterilized material into the laminar air flow.
6.2.3  Collect the samples at regular intervals of 0 hr, 24 hr, 48 hr, 72 hr, 96 hr, and 120 hr and perform the sterility test.
6.2.4  Collect the bottles at the interval as mentioned above and pour SCD medium into the bottle aseptically.
6.2.5  Collect the Miliflex cup at the interval as mentioned above and filtration 100 ml sterile water as per SOP; aseptically transfer membrane into SCD medium.
6.2.6  Collect the SS frits at the interval as mentioned above and transfer aseptically SS frit into 100 ml SCD medium.
6.2.7  Collect the tips at the interval as mentioned above and transfers aseptically tip into 100 ml SCD medium.
6.2.8  Incubate the samples at the specified temperature for 14 days (20-25°C for 7 days and 30-35°C for 7 days).

6.3 Acceptance Criteria
This study is carried out to establish the hold time of sterilized glassware and accessories after sterilization but no growth should be observed.
7.0 Conclusion
After a complete evaluation of the hold time study for sterile glassware and accessories used in microbiology lab a final hold time study summary report shall be prepared which should essentially contain discussion and conclusion which clearly determine the hold time period for sterile glassware and accessories.
