Erlenmeyer flasks

Nalgene Erlenmeyer Flasks are a safer alternative to glass. They won’t break, chip or shatter amid the bustle and bumps of everyday lab work. Enjoy their light weight and ease of handling. Trust Nalgene Erlenmeyer Flasks to be made from the highest quality laboratory-grade polypropylene copolymer (PPCO), polycarbonate (PC), polymethylpentene (PMP) and fluoropolymer (FEP) materials for dependably low extractables across a wide variety of lab applications.

Choose polypropylene for its low cost and good chemical compatibility with a wide range of lab chemicals. Get very good chemical resistance and clarity, too, with PMP. FEP provides the ultimate in chemical resistance, temperature range and inertness for the most demanding lab applications. Or, choose polycarbonate for its window-like clarity making it an ideal culture flask. Screw cap flasks are leakproof.*

 N Not recommended. Immediate damage may occur.

*The term “leakproof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2psig for 2 minutes, and no water escapes; b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes. Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leakproof at ambient temperature and pressure when used with their Nalgene closures.
^ Except oxidizing acids. For oxidizing acids, see “Oxidizing agents, strong.”
