Any deviation failure to meet these specifications will depyroogenation duly documented. Air does not move from dirty to clean. Name of the Testing Chemical: Suspend the 12 probes inside the vial and put into tunnel for Heat Penetration Study. Inoculate glassware or vials with a minimum of 5, EU of E. Air Borne Particulate Counter.

Air Borne Particulate Counter, duly calibrated with traceability certificate. Kaye makes a wireless temperature device and a thermal shield for tunnel applications. Connect the probes to suitable data logger, which can scan and print the actual temperature dwpyrogenation at different locations with respect to time.

Ankur Choudhary is India’s first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since The review highlight the theoretical concept of depyrogenation and the various tests performed for the qualification of Depyrogenation Tunnels. Operational Qualification Acceptance Criteria Setpoints. Traditional thermocouples have the issue of feeding into the tunnel and then the potential for them to move is present.

Rate of speed, minimum, maximum and nominal, will be measured and verified.


What type of thermosensors are you using? The objective of the test is to ensure that: Length of sterilizing zone. I persume the tunnel must be loaded with the glass vials selected as worst cases ; the thermosensors inserted on 8 vials runnel have them again pass through the tunnel for the requested period of time. To demonstrate that the system is capable of delivering air velocities, as per the Requirement, to maintain continuous laminarity of HEPA Filter installed in tunnel.


Then you can use your spiked vials to demonstrate adequate pyrogen destruction. Leakage in the filter should not be more than xepyrogenation. All critical thermocouples i. Name of testing instrument: Hello, I am wondering as to the Z-values to use deyprogenation verification of tunnel cooling zone sterilization. Shazia Assistant manager validation fgh yahoo.

After completion of sterilization cycle switch off the data logger. Non viable Air particle count test. Sterility means the complete absence dpyrogenation all viable microorganisms. I think you have a good start, your first test will show uniformity across the belt and through the tunnel.

To qualify such devices, various pharmacopoeias require depyrogenation devices to be periodically challenged with high levels of bacterial endotoxin.

HEPA Filter integrity testing. Purified Water System OQ. Purified Water System IQ. Then you can make a comparison between empty chamber FH values and full chamber FH values.

What I would like to ask has to do with the process of validation. Your help is very much appreciated, since I have to perform the validation tomorrow noon.

The BET indicators vials shall be placed next to the tunbel carrying the thermocouples. I am currently using a reference temp of C and a Z value of 20, however our operating setpoint isand I am calculating cumulative Fh values in the 20, minutes range.

Pharmaceutical Validations: Sterilizer cum Depyrogenating Tunnel Validation Protocol

For depy process you need to have more than 3 log of EU endotoxin unit and Fd greater trhen I have just entered another pharmaceutical company but the have not been using this equipment. Beyond the usual engineering aspects of validation with regard to specification, installation, commissioning, qualification, and calibration, the two important aspects of validation of dry heat processes ddepyrogenation thermal validation and endotoxin validation.


My question is, should the glass vials selected to carry the thermosensors be on the same line or theses glass vials should be selected randomly or based on a specific load schedule although we are referring to a tunnel? Can u help me buy providing a validation protocol in full detail.

Count 2 C 2. Sterility is the most important and absolutely essential characteristic of a parenteral product.

Eighty-five percent of thermocouples used must be operational upon completion of the study. The temperature distribution is uniform throughout the sterilization period. Maximum number of permitted particles per cubic meter equal to or above.

Should show at least depyrogenationn log reduction after exposing Sterilization temperature. I always run sensors with the pyrogen and calculate the FH too.

Also place one in the cold belt location from the empty chamber. A deviation indicates variance from the acceptance criteria however, does not necessarily mean that the qualification as unacceptable. Purified Water System PQ. Depyrogenation devices, such as tunnels, are used in the pharmaceutical industry to prepare components for aseptic validatiln. Minimum cumulative F H location will be determined for informational purposes only.
