It should be filtered with hot hydrochloric acid or chromic sulphuric acid before use for the FIRST TIME, and then rinsed with distilled water to remove any dust impurities that may be present in the filter.
After each use or after a certain period of time, an effective washing treatment must be carried out to prevent the filtration effect from being affected by the clogging of the filter holes by the sediment.
Glass filters are not suitable for the filtration of concentrated hydrofluoric acid, hot concentrated phosphoric acid, hot or cold concentrated lye. Please note that these reagents can dissolve the particles of the filter, causing the pores to expand or the filter to fall apart.
