Nalgene™ Straight-Sided Wide-Mouth Polycarbonate Jars with Closure, 125mL - FAQs

Why are some of your wide mouth bottles and jars not considered liquid leakproof?

This was a consequence of design and engineering limitations, and there was no practical way to incorporate the same level of seal integrity as our certified leakproof containers. While in many cases, they still hold up well to liquid containment applications, they have not been tested specifically for that purpose, and thus would be the responsibility of the customer to perform validation and risk management studies if necessary.
