Abstract
The invention relates to a sealed bag containing a reference fluid for the calibration or quality control of a sensor element for measuring body fluid parameters, the bag comprising peripheral walls of a first layered material. The bag further comprises an access port formed by an opening in the first layered material, wherein the opening is sealed by a cover of a second layered material, wherein the second layered material is more resistant to oxidation by the reference fluid than the first layered material.
