A common sight in most biology or chemistry labs: the laboratory squeeze bottle.
These bottles come in two main types: The Goose Neck Bottle and the Angled-Down- Spout (pictured)
These bottles “migrated” from my lab bench to my painting bench and are one of the most handy painting tools I have. To use, simply uncap and squeeze to deliver a controlled amount of your favorite cleaner, thinner, or paint: very handy!
With the Angle-Down Spout, wick the few drops left in the tip after use by gently tapping the tip against the airbrush paint cup or whatever container your adding fluid to. To seal, place the tight fitting silicone cap over the tip to prevent loss by evaporation.
These laboratory grade squeeze bottles are made out of PET plastic and will hold enamel and lacquer thinners for many years of use with no problem.
