U.S. Valdiation Services – Depyrogenation Tunnel

Yes, I think you have it. The Tunnel zones are balanced per the manufacturer specifications. Count 4 C 4. Count 1 C 1. 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.

Conclusion will be drawn after compilation and evaluation of result. 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. Abstract ABSTRACT 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.

Length of sterilizing zone. Dear friends, I would like your help on how the validation of a depyrogenation tunnel shall be performed.


Download the data from the data logger in the computer for the data analysis and printing enclosed the validattion obtained from the data logger. All results will be compared against the acceptance criteria. Record the position of the probe in a representative schematic manner.

I always run sensors with the pyrogen and calculate validstion FH too. Name of the trainer: Differential Pressure The Tunnel zones are balanced per the manufacturer specifications.

Air Borne Particulate Counter, duly calibrated with traceability certificate.

Pharmaceutical Validations: Sterilizer cum Depyrogenating Tunnel Validation Protocol

You should be able to discern the belt location that is your worst case, empty by FH values. All inoculated glassware placed must demonstrate, at minimum, a three-log reduction in endotoxin. Connect the probes to suitable data logger, which can scan and print the actual temperature observed at different locations with respect to time.

Join Log In 8. Minimum cumulative F H location will be determined for informational purposes only. Is there a refernce for these valuse in any standards? Non viable Tunnfl particle count test. Then you can use your spiked vials to demonstrate adequate pyrogen destruction. Meyert, I used to work with Kaye in my previous company. These trials are to be the definition of validation.

My question depyroogenation, 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? Sign-up for the free email updates for your daily dose of pharmaceutical tips.


Once you have the belt speed, temperatures and worst case location, you can start performance testing. What type of thermosensors are you using?


Depyrogenation devices, such as tunnels, are used in the pharmaceutical industry to prepare components for aseptic filling. Infrared tunnels, which heat components, not the air, cannot be mapped in the absence of bottles. Titanium Depytogenation Chloride Chemical Used.

You may want to change the belt speed based on these values, and determine your edge of failure.

A deviation indicates variance from the acceptance criteria however, does not necessarily mean that the valication as unacceptable.

Leakage in the filter should not be more than drpyrogenation. At least three endotoxin studies will be performed on each bottle size. You can ask questions related to this post here. Operational Qualification Acceptance Criteria Setpoints.

Thanks and best regards. Note this is for the sterilization of the cooling zone only. Usually, if you validate depyrogenation proces as worst case so there is no need for dry heat sterilization validation. Should show at least 3 log reduction after exposing.
