SOP for Loading Product Vials into Lyophilizers

Standard Operating Procedure for Loading Product Vials into Lyophilizers

1) Purpose

This SOP outlines the procedure for safely and accurately loading product vials into lyophilizers to ensure proper freeze-drying, uniform product exposure, and contamination prevention.

2) Scope

This SOP applies to all operators involved in the loading and arranging of product vials into lyophilizers for freeze-drying processes in accordance with the Batch Manufacturing Record (BMR).

3) Responsibilities

Operators: Responsible for loading vials into the lyophilizer according to the product’s specific lyophilization cycle requirements.
QA Personnel: Responsible for verifying that vials are properly arranged and ensuring compliance with contamination control measures.

4) Procedure

4.1 Preparing Product Vials

4.1.1 Pre-Loading Inspection

4.1.1.1 Inspect each vial for damage, contamination, or improper filling before loading. Reject any vials that show signs of defects.
4.1.1.2 Ensure that each vial has been sealed with a rubber stopper but is not fully crimped to allow for vapor exchange during freeze-drying.

4.2 Loading the Vials

4.2.1 Placement on Shelves

4.2.1.1 Arrange vials on the lyophilizer shelves in neat, evenly spaced rows, ensuring there is enough space between vials for uniform freeze-drying.
4.2.1.2 Load the shelves evenly to avoid temperature gradients and ensure consistent drying across the batch.

4.2.2 Monitoring Shelf Temperature

4.2.2.1 Ensure the shelf temperature is

within the acceptable range for the product to be freeze-dried. Monitor the temperature and adjust as needed.

4.3 Sealing and Starting the Cycle

4.3.1 Once the vials are loaded, ensure the lyophilizer door is sealed tightly to maintain vacuum integrity during the freeze-drying cycle.
4.3.2 Start the freeze-drying cycle according to the parameters specified in the BMR.

4.4 Documentation

Record the number of vials loaded, any rejected vials, and their positioning on the shelves in the Lyophilizer Loading Logbook. The operator and QA must verify all entries.
