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

These trials are to be the definition of validation. Suspend the 12 probes inside the vial and put into tunnel for Heat Penetration Study. All critical thermocouples i. Count 1 Depyrogenatiob 1. Typically tunnels run at a very high temperature and most stand alone sensors cannot withstand the heat.

Your help is very much appreciated, since I have to perform the validation tomorrow noon. To qualify the test the equipment should fulfill the acceptance criteria described in the individual test procedures.

To qualify such devices, various pharmacopoeias require depyrogenation devices to be periodically challenged with high levels of bacterial endotoxin.

Record the set parameters of the sterilization cycle to be operated during the test. Maximum number of permitted particles per cubic valiidation equal to or above. At least one heat penetration study using thermocouples will be performed on each vial size. Temperature uniformity and delivery of heat will be documented. Count 2 C 2.


Depyrogenation devices, such as tunnels, are used in the pharmaceutical industry to prepare components for aseptic filling. All instruments shall be calibrated before starting and after completion of validation studies. 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. Inoculate glassware or vials with a minimum of 5, EU of E.


A minimum of a three log reduction in endotoxin must be demonstrated. Yes, I think you have it. Compressed Air, Nitrogen, Vacuum, etc. The objective of the test is to ensure that: 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.

Infrared tunnels, which heat components, not the air, cannot be mapped in the absence of bottles. All inoculated glassware placed must demonstrate, at minimum, a three-log reduction in endotoxin. Should show at least 3 validatlon reduction after exposing Sterilization temperature.

The tunnel will be temperature mapped to demonstrate consistency. Minimum cumulative F H location will be determined for informational purposes only. Dear Forum, What z-value and reference temperature value shall be used in calculating Fh for a depyrogenation cycle, using dry heat oven? 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 validdation referring to a tunnel?


Kaye makes a wireless temperature device and a thermal shield for tunnel applications. Count 4 C 4. No containers should be damaged, none hung up, or dislodged.

Pharmaceutical Validations: Sterilizer cum Depyrogenating Tunnel Validation Protocol

Air Borne Particulate Counter, duly calibrated with traceability certificate. Then you can make a comparison between empty chamber FH values tuunnel full chamber FH values. Visitors are also reading: The unit is supplied with heat resistant HEPA filters Operational Qualification In addition to the common requirements outlined in the “General” section, the tunnel differential pressures prevent air travel from the dirty to clean areas.

Differential Pressure The Tunnel zones are balanced per the manufacturer specifications. You should be able to discern the belt location that is your worst case, empty by FH values. We are having the Sterilisation tunnels for both amp.
