The ROTIDRY® solvent without septum, identified as Dichloromethane (CAS: 75-09-2), is a halogenated hydrocarbon and an organic chlorine compound with a Molecular Weight of 84.93 g/mol. It is commonly known as Methylene chloride. This substance requires workplace precautions such as wearing safety goggles and gloves. The recommended indicative occupational exposure limit value for the European Union is 8 hours limit value: 353 mg/m3 (100 ppm), and short term limit value: 706 mg/m3 (200 ppm). A national occupational exposure limit value must be set due to the risk of percutaneous absorption.
