Version: 1.0
Effective Date: [Insert Date]
Reviewed By: [Insert Reviewer Name]
Approved By: [Insert Approver Name]
Objective
To validate the Aqueous Buffer Preparation Tank for the preparation of the aqueous phase in the production of liposomes and lipid nanoparticles, ensuring compliance with specified acceptance criteria.
Scope
This protocol applies to the Operational Qualification of the Aqueous Buffer Preparation Tank used in R&D and production areas for NDDS applications.
Responsibilities
The Validation Team is responsible for executing this protocol, while the Quality Assurance team will review and approve the documentation.
Prerequisites
- Installation Qualification (IQ) must be completed and approved.
- All personnel involved must be trained on the operation of the equipment.
Equipment Description
The Aqueous Buffer Preparation Tank is designed to prepare aqueous solutions with precise control over critical parameters such as pH, conductivity, and temperature. The tank is equipped with a mixing system to ensure homogeneity of the solution.
