<p>The invention relates to a bag (2) that includes: a first closed inner casing (1) made of at least one non-porous plastic material having a high barrier capacity to gases and delimiting a first space (6) forming stricto sensu a bag (1) capable of receiving the biopharmaceutical material or device, a second closed outer casing (8) made of at least one non-porous plastic material having a high barrier capacity to gases and defining a second space (9) in which the stricto sensu bag (1) is arranged, spacing means (11), at least one selected tracing gas provided in the first space (6) or in the second space (9) outside the stricto sensu bag (1), with a partial pressure higher than that in the second space (9) outside the stricto sensu bag (1) or in the first space (6), at least one colorimetric detector (12) reacting to the concentration of the at least one tracing gas by passing from a first color to a second different color, the at least one colorimetric detector (12) being provided in the second space (9) outside the stricto sensu bag (1) or in the first space (6), respectively.</p> |
