Manufactured from 33 expansion, low extractable borosilicate glass.

• Funnels have a high resistance to chemical attack and mechanical and thermal shock
• The KIMAX® 58° funnel promotes faster, more effective filtering because the cone is suspended by its uppermost edge, leaving most of the conical area for filtration

Constructed with a strong, molded rim, heavy uniform walls, and a fire-polished stem for a long service life.
