Should I clean my Findenser? If yes, how?

The wetted parts of Findenser (the parts that come into contact with solvent during normal use, i.e. the inner body and the cone/socket) are made from borosilicate glass 3.3.  This has very good chemical resistance (see TB 101 Glass Technical Data sheet available here).  We would still recommend that chemicals are washed off, however.

You should limit contact of the outer parts of Findenser with any corrosive chemicals you are using.  You should wash off any spills as soon as possible, and also ensure there is not a significant concentration of corrosive chemical vapours in the air around the Findenser.

Our recommended Findenser cleaning procedure is:

• Flush the internal glass surfaces with a suitable cleaning solvent such as acetone or IMS.  This is best achieved with a wash bottle.  External exposed glass surfaces may also be cleaned with a suitable solvent.  Allow washing solvent to drain into a suitable receptacle.
• Wash the whole Findenser assembly in warm soapy water, using a soft brush to clean fins.
• Rinse with warm water both internally and externally.
• Allow to air dry.

If necessary, Findenser may be cleaned in a dishwasher; however, care must be taken to limit the temperature to 50˚C, or the plug/seal may be damaged.
