Fill these air-and liquid-tight bottles directly from your line to store, test, and ship liquids. Connect to a quick-clamp fitting (also known as tri-clamp) with the included seal and clamp to fill, then secure the contents with the lid. Bottles are 316L stainless steel, which is easy to clean and does not react to the acids and alkalies in food, or chemicals such as sulfuric acid. The extra-smooth interior is polished to prevent product buildup and inhibit bacteria growth. These bottles are engraved with lot numbers for traceability and include a material test report.
