Disposable membrane
The invention relates mainly to an apparatus comprising a chamber for physically and/or chemically treating one or more samples or products, said apparatus comprising a door for introducing samples inside the apparatus chamber or bringing samples outside the apparatus, said apparatus comprising a membrane or film defining a chamber wall inside said apparatus when the door is closed.
1. An apparatus comprising a chamber for physically and/or chemically treating one or more samples or products, said apparatus further comprising a door adapted for moving between a closed position and an open position for introducing the one or more samples or products inside the chamber or bringing the one or more samples or products outside the chamber, said apparatus further comprising a membrane or film for isolating the chamber from the outside atmosphere, said membrane or film defining a chamber wall inside said apparatus when the door is in the closed position, said membrane or film including a sealable passage for passing the one or more samples or products through the membrane or film into the chamber, wherein said membrane or film comprises a proximal end and a distal end, said proximal end comprising an inlet to the passage and said distal end defining a section essentially complementary to a periphery of said chamber, said distal end of said membrane or film comprising a fold in which an inflatable seal is inserted, said fold being inserted in a channel extending along the periphery of the chamber to isolate a chamber inner part from a chamber outer part.
2. The apparatus of claim 1 , wherein said membrane or film comprises a joint or seal for sealing the membrane or film along a periphery of the chamber.
3. The apparatus of claim 2 , further comprising a channel along the periphery for receiving the joint or seal.
4. The apparatus of claim 3 , wherein said joint or seal is inserted within a fold in the membrane or film.
5. The apparatus of claim 3 , wherein said chamber forms part of a device selected from the group consisting of an oven, a drying equipment, a dryer, a freeze-dryer, an autoclave, a sterilizer, a gas chamber, and a depyrogenation apparatus.
6. The apparatus of claim 2 , wherein said joint or seal is inserted within a fold of the membrane or film.
7. The apparatus of claim 1 , wherein said membrane or film is made of a material selected from the group consisting of a polymer selected from the group of a thermoplastic, a polyethylene (PE), a polypropylene (PP), a polyaryletherketone, a PEEK (Poly(ether ether ketone), in particular poly(oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene); a polytetrafluoroethylene (PTFE); a perfluoroalkoxy (PFA) polymer; a poly(tetrafluoroethylene-co-perfluoromethyl vinyl ether) (MFA); a polyperfluoro(ethylene-co-propylene) (FEP); a poly(ethylene-alt-chlorotrifluoroethylene) (ECTFE); a poly(ethylene-co-tetrafluoroethylene) (ETFE); a poly(vinylidene fluoride) (PDVF); a tetrafluoroethylene-co-hexafluoropropylene-co-vinylidene fluoride terpolymer (THV); a poly(bisphenol A-co-4-nitrophthalic anhydride-co-1,3-phenylenediamine) (PEI); a poly(4-methyl-1-pentene) (PMP); and suitable mixtures thereof.
8. The apparatus of claim 1 , wherein a closure is provided for closing the passage through the membrane or film into the chamber, and wherein said closure in an open position allows the passage of the one or more samples or products.
9. The apparatus of claim 1 , wherein said film or membrane comprises one or more gloves for manipulating the one or more samples or products inside said chamber.
