Filling Funnels

Filling Funnels
Filling funnels are noted for their short, wide stem, which is excellent for filling bottles or transferring powders. Funnels typically have a 60 degree-angle that permits accurate fitting of filter paper, as well as vents or flutes that decrease filtering time. Glass filling funnels include a strong beaded edge that resists chipping, while the resistant structure of glass filling funnels allows for the use of various reagents and chemicals. The funnels, typically constructed from borosilicate glass, have a high resistance to thermal and mechanical shock, as well as chemical attack.
