List of Parameters: LXXX-001AB
Note: If the “Number of Pages” column is blank, all relevant documents contributing to the test result must be attached to the qualification binder. Ensure that all test documents are marked, and the first page is stamped as a “Qualification Document.”
Required Instrumentation and Auxiliary Means
This section outlines the necessary tools, equipment, and supporting materials required to conduct the Clean-In-Place (CIP) process efficiency test in a freeze dryer. Each listed item plays a crucial role in ensuring accurate testing and validation.
1. Type of Equipment
This refers to the specific machinery or tools used in the CIP process, such as the freeze dryer unit, spray nozzles, or automated cleaning systems. The equipment must be appropriate for the test and function correctly.
2. Type, Model/Version Number
The specific model or version of the equipment being used must be recorded to ensure consistency in testing. This information helps track changes, compare performance over time, and comply with regulatory documentation requirements.
3. Serial Number
The unique identifier assigned to each piece of equipment. Recording the serial number ensures traceability and accountability in case of performance issues or future inspections.
4. Valid Until
Some instruments or auxiliary means, such as UV lights or riboflavin solutions, may have an expiration date or a recommended validity period. Ensuring that all materials used are within their valid period guarantees the reliability of test results.
5. Riboflavin/B2 Vitamin
Riboflavin (Vitamin B2) is used as a fluorescent tracer in CIP efficiency testing. When exposed to UV light, riboflavin glows, allowing testers to visually inspect areas that have been effectively cleaned. Any remaining traces indicate insufficient cleaning.
6. UV Light
Ultraviolet (UV) light is used to detect riboflavin residues. The UV light causes riboflavin to fluoresce, making it easier to identify areas where the cleaning process may have been incomplete.
Purpose of This Section
By ensuring that all required instrumentation and auxiliary means are available and properly documented, the CIP process can be validated effectively, ensuring a high standard of cleanliness and compliance with industry regulations.
Acceptance Criteria: A visual inspection under UV light must confirm that the entire interior is sprayed with riboflavin/B2 vitamin. Any traces of riboflavin should not exceed 4% of the total surface area.
Implementation
- Follow all instructions provided in the test documents.
- The freeze-drying unit must be switched on, with all supply media connected and functioning.
- No failure messages that could impact the process should be displayed on the SCADA system.
- The assigned tester must be appropriately authorized to access the freeze-drying unit and SCADA system.

Performance of Test
The verification of CIP efficiency follows the procedure outlined in LOEE1507-001A-1.
Step 1: Pre-CIP Riboflavin Application
- Open the freezer dryer chamber door.
- Spray a maximum of 3000 ml of water containing 0.5 g riboflavin/B2 vitamin per liter onto the entire interior surface using a spray bottle.
Acceptance Criteria: A visual check with UV light must confirm that all shelves are adequately sprayed with riboflavin/B2 vitamin.
Step 2: Drying Process
- Leave the chamber door open.
- Initiate manual shelf heating to evaporate water from the solution.
- Heat the shelves to 40°C for approximately 120 minutes.

Step 3: CIP Process Execution
- Once the riboflavin solution has dried, enter the CIP process ID LOT1507-001C-1 and initiate the CIP cycle.
- Upon completion of the CIP process, perform a UV light inspection to assess cleaning efficiency.
- Document any detected riboflavin traces in the provided table.
- Properly describe and locate the affected areas for further cleaning validation.
- Estimate the affected area and calculate the ratio against the total surface area.

By following these procedures, the efficiency of the freeze dryer CIP process can be verified and maintained to ensure compliance with quality and regulatory standards.
Acceptance criteria: trace amount of riboflavin do not exceed 1% of total surface area
Summary
The efficiency of the freeze dryer CIP process is assessed using riboflavin/B2-vitamin as a tracer and UV light for detection. The test involves spraying the freezer’s interior with a riboflavin solution before initiating the CIP cycle. After the process, a visual inspection under UV light determines whether any traces of riboflavin remain. Acceptance criteria require that riboflavin residues do not exceed 1% of the total surface area. Any remaining traces are documented for further cleaning validation. Compliance with these criteria confirms the effectiveness of the CIP process.
Conclusion
A properly functioning CIP system is crucial for maintaining hygiene and efficiency in freeze-drying operations. The test results indicate whether the cleaning process effectively removes riboflavin/B2-vitamin residues, ensuring compliance with industry standards. If riboflavin traces exceed the acceptable limit, further validation and optimization of the CIP process are required. By following this procedure, manufacturers can uphold stringent cleanliness standards and improve equipment reliability.
