4.5.1 Resistance of Special Materials
4.5.1.1 Air LiHa Tip Cone
The Air LiHa tip cone and the inline filter may be moistened with aerosols from the sample
liquid.
The chemical resistance of the gold-plated brass tip cone depends on temperature and ex-
posure time. The inline filter is made of polyethylene, its chemical resistance is compara-
ble with the one of polypropylene (PP).
When pipetting aggressive liquids or strong solvents, check the Air LiHa tip cone for corro-
sion and replace the inline filter if it is not clean any more.
