About Caps

Laboratory closures like rubber stoppers, plugs and caps provide firm, secure closure of vessels, vials, test tubes and flasks that may or may not contain some highly hazardous chemicals should their contents be spilled in the workplace or lab. Have a set of beakers or Erlenmeyer flasks that need proper stoppage? Just double check the diameter of the vessel’s opening or aperture, and you’re on your way to safe, reliable storage. You can also find a wide range of different colored drop tip caps. For more laboratory supplies, browse our selection of culture and test tubes, vials and flasks.
