The exclusive SNAPTWIST™ closures are made of high flow polypropylene and are a true time saver.

The vials can be securely sealed by simply snapping the caps on. The ease with which these caps can be manipulated elimates the danger of spillage associated with other push-on/pull-off caps. A built-in positive lock prevents the cap from popping off because of a small build-up of pressure in the vial. The quality of the sealing system is such that it is not necessary to tighten the closure with pressure to achieve a leakproof seal.
