13mm Caps

This assortment of 13mm caps and closures are designed to fit the following closure designs: 13-415 and 13-425 thread finishes, as well as 13mm Autosampler snap caps (for glass autosampler vials) and 13mm caps designed only for Nalgene® micro packaging vials. Please note that caps are not universal, so 13mm caps will not necessarily fit a 13mm opening. Request the specific closure design from your container manufacturer before selecting closures.
