Amber polypropylene screw caps
Nalgene LDPE, HDPE, PP and PMP containers can be used for long-term storage, but direct UV exposure should be avoided.
Nalgene reusable HDPE bottles are designed to last many years under typical laboratory conditions. Yet, as with all durable products, they need to be retired and replaced eventually. Nalgene HDPE bottles and their packaging are readily recyclable. Please recycle the corrugate cartons and LDPE bags in which your Nalgene bottles products are packaged. And at end of product life, please wash and recycle your Nalgene HDPE bottles.
† 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.
