1 oz Amber Glass Bottles

About

Small bottle. Serious protection. These 1 oz amber glass Boston round bottles are built for products that can't afford light exposure — essential oils, tinctures, serums, and pharmaceutical formulations that need UV-filtering packaging from day one. Available in standard amber and frosted amber finish, both with a 20-400 neck that fits the full range of droppers, screw caps, and child-resistant closures. Sold wholesale by the case (360 units).

The iron, manganese, and sulfur compounds in amber glass absorb UV and near-visible light — the wavelengths most likely to degrade active ingredients, oxidize oils, or break down botanical extracts over time. If you're packaging anything light-sensitive, amber isn't just an aesthetic choice. It's functional protection built into the material itself. And because it's glass — not plastic — it's chemically inert, non-porous, and won't absorb or leach into your product. Who Uses 1 oz Amber Glass Boston Round Bottles?
