This bottle is a 15mL euro round glass bottle with a 18-DIN neck finish and is sold by the case (390 count). The euro bottle has rounded shoulders and a rounded base, but it is specifically designed to be fitted with tamper-evident, child-resistant, or standard closures with inverted pipettes. Glass has high clarity, can be colored, has high chemical-resistance levels and extremely high resistance to heat and cold. It is great for storing oils. The matching dropper assemblies are available in multiple closure styles and are equipped with the DripTrap patented bulb, which eliminates leaking. There is also an option for graduated pipettes, perfect for accurate dosing.
