Pneumatic Polypropylene Trough

Use this timesaver for virtually any gas-collecting need. Setup is fast and easy with a built-in bridge that won't get lost, so the gas supply inlet can't be flooded. It is constructed of impact-resistant polypropylene that is lightweight and virtually unbreakable. It holds four 8 oz. bottles (not included); and the inlet connection and overflow outlet take ¼" Int.Ø tubing (not included).
