Abstract

A single use bag for storing a material. The single use bag includes a two layers of which one of the two layers is in contact with the material container within the bag. The layer which is in contact with the material contained within the bag is an active layer. The active layer may be made active by incorporating a scavenger into the layer. At least one layer of the single use bag may include a fluoropolymer.

First claim

We claim:

1. A storage system for storing a liquid medium, comprising: a single use bag including at least two layers,
wherein a first layer of said at least two layers is a fluoropolymer layer and a second layer of said at least two layers is a first active layer, and
wherein a third layer of the at least two layers is a second active layer, the second active layer including a covalently attached receptor configured to bind to an impurity.

2. The storage system of claim 1 , wherein said first active layer includes a scavenger.

3. The storage system of claim 1 , wherein said ‘first layer is an internal surface layer.

4. The storage system of claim 3 , wherein said first layer is perfluoroalkoxy.

5. The storage system of claim 1 , further comprising at least one additional layer in addition to said the first layer, the second layer, and the third layer.

6. The storage system of claim 5 , wherein said second layer is a core layer and said at least one additional layer forms an outer surface layer of said single use bag.

7. The storage system of claim 6 , wherein said at least additional layer forming said outer surface layer of said single use bag is polytetrafluoroethylene.

8. The storage system of claim 1 , wherein the first active layer comprises a desiccant.

9. The storage system of claim 8 , wherein said desiccant is selected from the group consisting of silica gel, alumina, calcium sulfate, calcium chloride, montmorillonite clay, and molecular sieves.

10. The storage system of claim 1 , wherein the first active layer is configured to trap oxygen.

11. The storage system of claim 1 , wherein the first active layer is selected from the group consisting of iron, sodium, and lithium.

12. The storage system of claim 1 , wherein the first active layer comprises a carbon-based compound configured to trap organics.
