Often used to clean glassware or tubing, these bottles have a valve that lets you dispense liquids upside down or at any angle. Colored lids and labels help you identify their contents at a glance. Each label has a National Fire Protection Association (NFPA) diamond, which uses colors, numbers, and abbreviations to help first responders quickly recognize hazards. A vent keeps pressure from building up and causing drips. These bottles are also known as wash bottles.

Bottles with labels that meet GHS standards are marked with their contents and key hazard information, including health risks. The Globally Harmonized System includes pictograms that were designed by the United Nations to clearly identify chemicals as flammable, toxic, corrosive, and more.

Swap a spray adapter (sold separately) with the nozzle to convert these bottles into spray bottles. These adapters only spray when the bottle is upright.
