This 15ml (0.5 oz) dropper bottle is useful to dispense liquids one drop at a time. It works well for indicator solutions and stains. It has a removable dropper tip that snaps into the neck of the bottle and a white polypropylene cap. The natural LDPE plastic is chemically resistant and suitable for storing most solutions. However, do not use this dropper bottle with concentrated acids and bases or strong solvents.
