Screw Thread Diagnostic Bottles and Vials are an alternative to crimp / serum finish bottles and vials. When used with either thin flange stoppers and closures or with the Wheaton I-Loc™ Closure, they offer all the advantages of an aluminum seal and stopper with the convenience of a screw closure. The unique combination of a stopper and screw closure ensures excellent sealing characteristics making them ideal for liquid reagents. The contents can be accessed using a syringe through the stopper or the screw closure can be easily removed to decant the contents. There is no need for crimping or decrimping devices.
