PURPOSE:To prevent the contamination of the outside with bacteria by placing a hydrophilic element on the gravity side of a hydrophobic element when a substance having possibility containing microbiological contaminant is passed through a filter consisting of both elements from a high pressure steam sterilizing device. CONSTITUTION:A hydrophobic element 1 and a hydrophilic element 2 are set to the discharge piping routes 17, 18 of a high pressure steam sterilizing device 11 in such a state that the hydrophilic element 2 is positioned on the gravity side with respect to the hydrophobic element 1. When air, steam and condensed water are discharged, air and steam are filtered by the hydrophobic element 1 of a filter element 3 and also filtered by hydrophilic element 2 not wetted with condensed water. After the elements 1, 2 are wholly wetted with condensed water, air and steam are discharged only from the hydrophobic element and condensed water is discharged only from the hydrophilic element. Therefore, air, steam and condensed water can be smoothly discharged. |
