Shazia Assistant manager validation fgh yahoo. 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.

To determine cold spots. Rate of speed, minimum, maximum and nominal, will be measured and verified. The oven must meet specifications for total particulates.

Dear Gigastrom, If you validatlon have any problem regarding tunnel qualification and validation of sterilization cycle then you can ask freely.

Name of testing instrument: These trials are to be the definition of validation. I will tuhnel using C for two hours for the depyrogenation process.


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? Dear Forum, What z-value and reference tunnfl value shall be used in calculating Fh for a depyrogenation cycle, using dry heat oven? Any deviation failure to meet these specifications will be duly documented. Operational Qualification Acceptance Criteria Setpoints.


Ankur Choudhary is India’s first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since Purified Water System OQ.

Data Logger with Minimum 12 Probes duly calibrated.

Click here for advertising rates! For over kill approach you can icrease the sterilization time in hot zone. Record the position of the probe in a representative schematic manner. Usually, if you validate depyrogenation proces as worst case so there is no need for dry heat sterilization validation.

At least three endotoxin studies will be performed on each bottle size. Count 1 C 1.

Meyert, I used to work with Kaye in my previous company. What type of thermosensors are you using? A deviation indicates variance from the acceptance criteria however, does not necessarily mean validaton the qualification as unacceptable.

Comments shall be published after review. Inoculate glassware or vials with a minimum of 5, EU of E. Is there any correlation graphy is there for Vs for finding the D value.


Visitors are also reading: You may want to change the belt speed based on these values, and determine your edge of failure. Traditional thermocouples have the issue of feeding into the tunnel validwtion then the potential for them to move is present. Air flow pattern should be unidirectional and non turbulent.

Count 4 C 4. Differential Pressure The Tunnel zones are balanced per the manufacturer specifications.

Pharmaceutical Validations: Sterilizer cum Depyrogenating Tunnel Validation Protocol

Dear Meyert thank you very much for your quick response. Typically tunnels run at a very high temperature and most stand alone sensors cannot withstand the heat. Negative valldation pyrogen free water must not exhibit a level of endotoxin above the minimum sensitivity of the reagent used. Leakage in the filter should not be more than 0. We are trying to shorten our oven depyrogenation cycle from 3 hrs dwell at C to 15 min dwell C. Get Free Updates Again thank you very much.

Should show at least 3 log reduction after exposing Sterilization temperature. Compressed Air, Nitrogen, Vacuum, etc.
