Packaging
Due to quality and safety aspects Ammonia Solution will no longer be offered in glass bottles but solely in HDPE bottles.

Please note the following replacements:
1054231000 (1 L glass bottle) replaced by 1054231011 (1 L HDPE bottle)
1054232500 (2.5 L glass bottle) replaced by 1054232511 (2.5 L HDPE bottle)
