Findenser is resistant to the majority of solvents and splash-resistant to dilute acids and alkalis at room temperature. Extended exposure to acids or alkalis will attack the outer metal surface of the Findenser. It is important to clean off any chemical spills immediately after they occur.
The inner body of Findenser and the cone/socket, i.e. the wetted parts that come into contact with the substance being evaporated during normal use, are borosilicate glass 3.3, which has very good chemical resistance. The metal finned jacket is anodised aluminium and the plug and seal are acetal and HT silicone.
