Kaye makes a wireless temperature device and a thermal shield for tunnel applications. For over kill approach you can icrease the sterilization time in validxtion zone. Performance Qualification PQ Heat penetration studies: Titanium Tetra Chloride Chemical Used.

Thank you both for the clarifications. Then you can make a comparison between empty chamber FH values and full chamber FH values.

All results will be compared against the acceptance criteria. Click here for advertising rates! Post Job for Free.

Semi-flexible metal temperature sensors allow for some freedom in logger placement while maintaining the placement of the sensor, to ensure that the hardest-to-heat location temperature is depurogenation in the study data. Physical handling of containers will be monitored. Comments shall be published after review. Name of testing instrument: Dear Meyert thank you very much for your quick response. There are typically three zones: The hardest-to-heat locations are determined by the location with the lowest lethality value FH during the empty chamber mapping, and the item with the lowest lethality during item temperature mapping.


Hi Dear Shahnawaz Plz let me know regarding the calculation of 3 log reduction of endotoxins in case of tunnel validation. Air Borne Particulate Counter.

Depyrogenation Oven and Heat Tunnel Qualification

Ellab offers an extensive catalog of validation equipment that is designed for the qualification of dry-heat sterilizers, and our validation staff are well experienced in writing and executing the necessary validation documentation for your depyrogenation oven or tunnel qualification.

Name of the trainer: Eighty-five percent of thermocouples used must be operational upon completion of the study.

To qualify the test the equipment should fulfill the acceptance criteria described in the individual test procedures. Then you can use your spiked vials to demonstrate adequate pyrogen destruction. Length of sterilizing zone.

Visitors are also reading: Data Logger with Minimum 12 Probes duly calibrated. Whether the fumes of the titanium tetra chloride follow unidirectional path. Traditional thermocouples have the issue of feeding into the tunnel and then the potential for them to move is present.


Record the position of the probe in a representative schematic manner. Name of Testing Instrument: This website uses cookies to improve your experience. Pyrogens are thermally stable and are not removed though common sterilization processes, such as autoclaving, but extended exposure to elevated temperatures will remove them.

Join Log In 8. Purified Water System PQ. Purified Water System OQ. The stream of air should be unidirectional and non-turbulent upto working zone. A deviation indicates variance from the acceptance criteria however, does not necessarily mean that the qualification as unacceptable.


Name of the Testing Chemical: Total Particulate Counts The oven must meet specifications for total particulates. Negative controls pyrogen vapidation water must not exhibit a level of endotoxin above the minimum sensitivity of the reagent used. Purified Water System IQ. We are trying to shorten our oven depyrogenation cycle from 3 hrs dwell at C to 15 min dwell C.

Any deviation failure to meet these specifications will be duly documented. Additionally, door interlocks should be used tujnel both safety and to prevent flow between clean and dirty process areas. Therefore, I will have to proceed with the existing means. The oven must meet specifications for total particulates.
