This 32-ounce solid brass sprayer can be pressurized from any standard air supply (air compressor, service station, bicycle pump, etc.). It is available with an optional CO₂ charging kit for use in places where an air supply is inaccessible. Use it for any chemicals you wish to spray, such as Ninhydrin, Small Particle Reagent, etc. Be aware, however, that some solvents will dissolve the paint from the sprayer and some solvents should only be used in a fume hood or other controlled situations.
