Beschreibung

Packaging

Aus Qualitäts- und Sicherheitsgründen ist Ammoniaklösung nicht mehr in Glasflaschen, sondern ausschließlich in HDPE-Flaschen erhältlich.

Bitte beachten Sie die folgenden Ersetzungen:
1054231000 (1-Liter-Glasflasche) ersetzt durch 1054231011 (1-Liter-HDPE-Flasche)
1054232500 (2,5-Liter-Glasflasche) ersetzt durch 1054232511 (2,5-Liter-HDPE-Flasche)
