The 4-liter amber glass bottle with distinctive finger grip is as common in most labs as Parafilm® and pipettes.  Used by many chemical manufacturers as the containment vessel of choice for solvents, these bottles are (thankfully) supplied with a more-or-less standardized finish: the “GL38” 38-430 glass thread.  Although compatible with 38-430 caps used on some plastic bottles - such as Nalgene - it’s important to note that the GL38 caps supplied here are not deep enough to engage and seal on many plastic 38-430 bottles.
