For those DIYers doing ozone therapy at home...don't pay 100-200 for ozone glassware for a bottle the size of a spice jar! You can make your own for 1/4 the retail price. I came up with making the necessary glassware candle jars and cylindrical vases. You can use any glassware you have ..just be sure they make the silicone plug it's mouth diameter size first. I bought silicone stoppers from auto painting parts store, a glass core drill bit and some cylinder vases, aquarium stones and I got more for my buck! I've been working with it for some time now and I'm very pleased with my setup. It can quick disconnects ( with quick connectors) for refrigerator storage and then back to setup use. PS ...be sure to buy the core drill the next size up from your tube size. I bought 5/16ths for my 3/16ths tubing. Your tubing may vary.
