Abstract
A container comprising a flexible semi-permeable composite membrane structure is described, as well as its applications. The membrane has a low molecular weight cut-off, comprises a flexible support layer thick enough to give strength to the membrane structure and having a relatively high molecular weight cut-off and, on at least one surface of the said support layer, a second layer having a relatively low molecular weight cut-off and is thin enough to allow a workable flux. Said container may be used for the preparation of rehydrated solute solutions, rehydrated blood or blood substitutes, nutritional solutions, solutions for medical purpose or of pure water.
