Plastic Funnels
Nalgene plastic funnels are a safer alternative to glass. They won’t break, chip or shatter amid the bustle and bumps of everyday lab work, and won't dent or corrode like metal funnels. Enjoy their light weight and ease of handling.
Trust Nalgene funnels to be made from the highest quality laboratory-grade polypropylene copolymer (PPCO), high density polyethylene (HDPE), low density polyethylene (LDPE), and polypropylene (PP) materials for dependably low extractables and compatibility with a broad range of lab materials.
With so many sizes and styles, there are Nalgene plastic funnels to serve a wide variety of lab applications.
