EISCO - Filter Funnel, Made of Borosilicate Glass 3.3, Chemical Resistant, Plain, 60° Angle, Dia. - 100 mm, Stem Length - 100 mm. Pack of 10

The quality of the funnels is very good. The seller is also responsive to customer complaints...which is very nice. When I purchased a lot of 10 funnels, few were broken in transit - but the seller promptly replaced them when I raised the issue. Much appreciated.

Nice product.
