Why do you recommend Teflon-coated bottles to store high-value contents such as, active pharmaceutical ingredients (API's), bulk intermediates, and critical reagents?

Teflon is ideal for storing the highest-value contents because it is resistant to most chemicals, temperatures, and processes, allowing for rigorous cleaning procedures such as those that require boiling nitric acid. Teflon also allows you to store contents down to cryogenic temperatures for products requiring ultra-low temperature (below -100 degrees C) storage.
We offer Nalgene Teflon bottles that provide excellent chemical and temperature resistance in a leak-proof design. They are manufactured using quality resins, with the added value of high-level support, making Nalgene Teflon bottles an ideal choice for your high-value contents.

Why are your Nalgene containers and caps always different materials?

In order to function as a leakproof system without a liner (one of the key advantages of our laboratory and packaging products), the surfaces of the container and closure that meet and push together when tightened must be dissimilar materials with different hardnesses. Even our polypropylene copolymer (PPCO) bottles with polypropylene homopolymer (PP) bottles are different enough to function properly. On some larger carboy products, this difference cannot be sufficiently maintained so a pliable thermoplastic elastomer (TPE) gasket is added for proper leakproof seal function.
