The best jars for storing extracts, oils and other liquids are the Amber Boston Round glass containers. The Amber jars come in a variety of sizes (1 oz., 2 oz. 4 oz., 8 oz., 16 oz., and 32 oz.) and offer UV protection for light-sensitive products and have a narrow mouth for precision pouring. Our customers have used these jars for DIY cleaning liquids, bitters, specialty drinks, extracts (like our homemade vanilla extract) and so much more. The Boston Round jars are also available in clear glass if you don’t need the amber. Browse our entire line of Boston Round bottles to see which one fits your need best.
PolyCone Lined Phenolic Caps
The lids for the Amber jars are pretty cool! The jars use the PolyCone Lined Phenolic Caps. The caps form an exceptionally tight seal and provide a good chemical barrier. The cone shaped liner allows for a superior seal because it molds itself around the sealing area of the finish on the glass bottles. It is constructed of an oil-resistant plastic, which makes it a great match for oils, essential oils, solvents and liquids that require more care in storage or that could be caustic to your average lid. Pairing our Amber glass containers with PolyCone lids creates an excellent storage option for extracts, oils, brews, chemicals, medicines and other valuable liquids.
Also available are Dropper Caps which are ideal for measuring out small amounts of liquids. We offer dropper caps that pair with our 1 oz, 2 oz, and 4 oz jars. Whether you are making your own tinctures, custom fragrances or essential oil blends our dropper will become indispensable.
The easiest way to fill these jars is with our Mini Stainless Steel Funnel. It’s the perfect size to transfer herbs, spices, extracts, oils and other liquids into the Amber jars without risking spillage.
We also have heat shrink bands to fit all of our Boston Round Bottles, which are compatible with the phenolic lids in addition to the droppers. If you are unsure of sizing, we have the proper heat shrink bands listed in the “accessories” tab of each relevant container.
