Tamper Evident Closures

Thermo Scientific™ Nalgene™ Tamper Evident Closures feature a tamper-evident break ring design which combines the unique leakproof* nature of the Nalgene bottles/closure system with the possibility of ensuring proof of content integrity. Detachment of the seal ring readily provides evidence of the  improper use or intentional opening of the media bottle.

The easy application and breaking of the tamper-evident seal ring eliminates the need for shrink bands, providing both a tamper-evident and leakproof-guaranteed system in a single, cost-effective step.

* The term "leakproof" applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100 mm, after they are filled with water, inverted, withstand air pressure of 2 psig for 2 minutes, and no water escapes; b) Bottle/funnel/flask closure systems of larger than 100 mm 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.
