This general-purpose vial can be used for liquid scintillation counting, gamma counting, chromatography, sample storage, and culturing. It will fit very nicely into the LKB and Packard Varisette counters. The shoulderless vial features a full-width opening of 12.5 mm, and the dimensions are 16 x 57 mm. 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; removing the caps requires an easy 1/4 turn (twist). The ease with which these caps can be manipulated eliminates 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 pressure build-up in the vial. The quality of the sealing system is such that it is unnecessary to tighten the closure with pressure to achieve a leakproof seal.
