Title: PROTECTED FILTER UNITS FOR SAFETY FILTRATION AND METHOD FOR PRODUCTION THEREOF
Abstract:
The invention relates to protected filter units for safety filtration, in which the filter units are at least double-packed with different packaging materials and to a method for producing the protected filter units. In this case, the first packaging material is permeable to gases but impermeable to microorganisms and the at least second packaging material is impermeable to gases. The first packaging material fixes the at least one filter unit, and so no abrasion can take place during transport and handling. The filter units according to the invention are suitable for sterile filtration processes and for filtration processes under clean-room conditions.
