Typically tunnels run at a very high temperature and most stand alone sensors cannot withstand the heat. We are having the Sterilisation tunnels for both amp. Once you have the belt speed, temperatures and worst case location, you can start performance testing. You may tunbel to change the belt speed based on these values, and determine your edge of failure.

Thanks and best regards. Any deviation failure to meet these specifications will be duly documented. I am wondering as to the Z-values to use during verification of tunnel cooling zone sterilization. At least one heat penetration study using thermocouples will be performed on each vial size. Name of testing instrument: Compressed Air, Nitrogen, Vacuum, etc.


For over validdation approach you can icrease the sterilization time in hot zone. Physical handling of containers will be monitored. Operational Qualification Acceptance Criteria Setpoints.

I will be using C for two hours for the depyrogenation process. Comments shall be published after review. After completion of sterilization cycle switch off the data logger.

I am in the process of validating an oven for the depyrogenation process. Join Log In 8.

These trials are to be the definition of validation. Ankur Choudhary is India’s first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since Sign-up for the free email updates for your daily dose of pharmaceutical tips.

Depyrogenation Tunnel Validation – EQUIPMENT VALIDATION – Learnaboutgmp Community

Non viable Air particle count test. Thanks Shahnawaz for your reply, Just for my understanding, for a temperature of C, I would use a z-value of??

Negative controls pyrogen free water must not exhibit a level of endotoxin above validatlon minimum sensitivity of the reagent used. The mapping is therefore performed in the PQ.

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 are thermal validation and endotoxin validation. The review highlight the theoretical concept of depyrogenation and valodation various tests performed for the qualification of Depyrogenation Tunnels.


Inoculate glassware or vials with a minimum of 5, EU of E.


All results will be compared against the acceptance criteria. The oven must meet specifications for total particulates. Usually, if you validate depyrogenation proces as worst case so there is no need for dry depyroegnation sterilization validation.

Home Microbiology Depyrogenatiob Sterilization. Depyrogenation devices, such as tunnels, are used in the pharmaceutical industry to prepare components for aseptic filling. I persume the tunnel must be loaded with the glass vials selected as worst cases ; the thermosensors inserted on 8 vials and have them again pass through the tunnel for the requested period of time.

Whether the fumes of the titanium tetra chloride follow unidirectional path.
