swim was thinking more for using these type of funnels to filter mda.hcl, mdma.hcl, 2,5 dimethoxynitrostyrene, 2ch.hcl, or 2cb.hcl, not for pd/c, etc. would pdcl2 and cucl2 be filterable through these type of funnels? dissolved pdcl2 seems to stain swims regular buchner on the inside of the stem. pain in the ass to remove.
terbium,
swim knows there are regular gooch and hirsch funnels, but they do make them with sintered glass, check any chem equipment supplier.
