5.2.2.4 Other indirect contact part which not directly contact to the products should be stainless steel 304 or higher quality grade of materials, easy to clean and not generate particle by itself. The materials should have the MSDS for guarantee using in Pharmaceutical Company.
5.2.2.5 Mechanical part should be the materials that no rust, easy to clean and not generate particle by itself.
5.2.2.6 For all and each welding joints should have the certificate of welding and comply with the cGMP/PICs guideline.
5.2.2.7 All mechanical parts which require using the lubricant and having risk of lubricant can be contaminate with product, should be used with the Pharma grade lubricant only. For other mechanical parts with no risk of product contaminate with lubricant can be use the food grade lubricant. Certificate of lubricant should be attached in design qualification.
5.2.2.8 All nut and bulb should be smooth with the machine surface and no space for dust collected and the material should be the same as describe in 5.2.2.3 and 5.2.2.4
5.2.2.9 The machine should have clear covered closure cabinet and made from polycarbonate or tempered glass.
5.2.2.10 The machine should have the heat exhaust system and blower or mechanical part should not generate the particle to contaminate with the vials inside the chamber.
5.2.2.11 The depyrogenation tunnel machine should not break or make the defect of vials more than 0.5% and the broken vials from automatic vial washing process should easily to keep out by operator
5.2.2.12 The depyrogenation tunnel should consisted with 3 parts of chamber; pre-heat chamber, sterilization chamber and cooling chamber
5.2.2.13 The speed of conveyor should able to adjust and display in display monitor
"
"5.2.3 Vial loading process
5.2.3.1 The vials from automatic vial washing machine should directly move to depyrogenation with the rise up position of vials
5.2.3.2 The loading process should not generate the broken vials and any other defect such as crack vial, scratch vial, etc.
"
"5.2.4 Pre-heat chamber
5.2.4.1 The pre-heat chamber should heat up the temperature of the vials before though the sterilization chamber
5.2.4.2 The rest of water from the automatic vial washing machine should be remove in this chamber
5.2.4.3 The air using inside the chamber should be pass through at least H11 pre- filter with the common side and easily to purchase.
5.2.4.4 Certificate of filter should provide in FAT protocol and execution
5.2.4.5 The differential pressure between upper and lower of each filter should able to read by calibrated digital gauge
"
"5.2.5 Sterilization chamber
5.2.5.1 After heat up the vials from pre-heat chamber, the vials will pass though the sterilization tunnel for sterilization purpose.
5.2.5.2 The temperature for sterilization should more than 250°C and able to terminate at least 6 log reduction of Bacillus Sterothermophilus
5.2.5.3 The vials should have the lag time at the first vial coming inside the chamber to ensure that the sterilization temperature and time for sterilization should achieved
5.2.5.4 The differential temperature between cooling spot and hot spot should not greater than 3 °C
5.2.5.5 The temperature measurement by heating probe at least 9 position inside the sterilization chamber should comply at least 4 sigma statistical data.
5.2.5.6 The air using inside the chamber should be pass through at least H13 HEPA filter with the common side and easily to purchase.
5.2.5.7 Certificate of filter should provide in FAT protocol and execution
5.2.5.8 The differential pressure between upper and lower of each filter should able to read by calibrated digital gauge
