Pyrogens are thermally stable and are not removed though common sterilization processes, such as autoclaving, but extended exposure to elevated temperatures will remove them. Ovens should have an air pressure differential controlled to prevent deyrogenation from the dirty to clean sides of the unit.

Name of Testing Instrument: Data Logger with 12 Probes duly calibrated. My concept if I understand well, is exactly as yours.


The qualification of a depyrogenation oven or tunnel requires validation sensors that can withstand exposure to extremely high temperatures. 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 validahion based on a specific load schedule although we are referring to a tunnel?

Air flow pattern tunnnel be unidirectional and non turbulent. I am wondering as to the Z-values to use during verification of tunnel cooling zone depurogenation. 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. The objective of the test is to ensure that: Join Log In 8. This website uses cookies to improve your experience.


Therefore, I will have to proceed with the existing means.

Visitors are also reading: During execution of this protocol, if any deviation is noticed, the person executing the protocol initiates a deviation report and provides the detail description of the deviation. Load temperature mapping, which may include endotoxin challenge studies with inoculated samples.

To determine cold spots.

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.

Yes, I think you have it. In deed the thermosensors we are using have 6m length, therefore no problem on that. Your help is very much appreciated, since I have to perform the validation tomorrow noon. Shazia Assistant manager validation fgh yahoo. Thanks and best regards.

Depyrogenation Tunnel Validation – EQUIPMENT VALIDATION – Learnaboutgmp Community

Ankur Choudhary Print Question Forum 2 comments. 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. Thanks Shahnawaz for your reply, Just for my understanding, for a temperature of C, I would use a z-value of?? Also place one in the cold belt location from the empty chamber. As with the ovens, air differentials should be used to create sterile boundaries and prevent cross contamination between sections of the oven and process areas.


You may want to change the belt speed based on these values, and determine your edge of failure. For depy process you need to have more than 3 log of EU endotoxin unit and Fd greater trhen Record the position of the probes in a representative schematic form. Leakage in the filter should not be more than 0.

I am familiar with the theoretical concept of the validation i. Before we through this in the dark I would like to know if there is a minimum temp and lenght or valiration graph for EI reduction available so we can calculate then procced? Typically tunnels run at a very high temperature and most stand alone sensors cannot withstand the heat.

Is there a refernce for these valuse in any standards?

The tunnel will be temperature mapped to demonstrate consistency. Post Job for Free. Get Free Updates Titanium Tetra Chloride Chemical Used. All inoculated glassware placed must demonstrate, at minimum, a three-log reduction in endotoxin. Without knowing the tunnel configuration, could be the middle or one side.

The tunnel is a newly installed part of a newly installed line. Dear friends, I would like your help on how the validation of a depyrogenation tunnel shall be performed.
