Nalgene is a brand of plastic products developed originally for laboratory use, including such items as jars, bottles, test tubes, graduated cylinders, 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.
