Nalgene is a brand of plastic products developed originally for laboratory use, including such items as jars, bottles, test tubes, and Petri dishes, that were shatterproof and lighter than glass. The properties of plastic products make them suitable for work with many substances in various temperature ranges. Nalgene products are manufactured by Nalge Nunc International, which in 2004 became a subsidiary of Fisher Scientific, now Thermo Fisher Scientific. The name Nalgene is a registered trademark.
