How does OSR ensure that the compressed air used for door sealing does not leak into the cabinet?

First of all, OSR has strict requirements on processing technology, requiring that the sealing groove must be smooth and without edges to prevent scratches on the sealing strip. In addition, in order to facilitate real-time verification by customers, OSR has installed a set of pressure holding procedures for regular leak tests on the chamber.

The pressure holding test is used to verify that under vacuum, the amount of gas leaking into the sterilization chamber is not enough to prevent steam from penetrating the load, and will not cause the load to be contaminated again during the drying period. The qualified standard is that under extreme vacuum, the rate of pressure rise in the cabinet should not exceed 0.13kpa/min. OSR’s pressure holding procedure uses a pressure holding time of 16 minutes, a pressure holding pressure of -94KPa, and a leakage pressure of 2KPa. (Because the accuracy of the pressure sensor is 1KPa. 0.13kpa/min multiplied by 16 minutes equals 2.08KPa.)
