摘要

Ammonia precursor refilling device comprising a container storing an ammonia precursor in solid form; said container being configured to fit within a first volume during storage and to be enlarged to a second volume which is larger that the first volume; said container being provided with an opening which is closed by an opening mechanism; said second volume being measured for allowing the container to be filled through the opening with water in an amount sufficient to allow said ammonia precursor in solid form to be at least partially dissolved to form an ammonia precursor solution.
