Are your Nalgene containers tested for air shipment of liquid samples?

Most of our products are manufactured and tested for leakproof performance in laboratory and industrial settings only. Our PassPort IP2 bottles (2099 and 2199 series) represent the only exception to this: they are rigorously leak tested under a 15 psi (-95 kPa) pressure differential to simulate unpressurized air cargo transport.

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.
