A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware or to precisely fill volumetric flasks.
Design
A wash bottle consists of a plastic bottle, with the lid perforated by a plastic tube which is bent at one end. Some models have a detachable tip, which can be used to insert smaller amounts of liquid. Some models have the plastic tube attached sideways.
Wash bottles are often filled with deionized water, but can also be filled with various solvents, like alcohols, ethers, etc. Often, colors are used to differentiate between bottles: red (acetone), yellow (isopropanol), green (methanol), white (ethanol), etc. It should be noted that this color identification is not universal.
Availability
Wash bottles can be purchased from lab suppliers or online. Make sure to inspect the seal, as poorer quality wash bottles do not seal properly.
DIY wash bottle
A simple wash bottle can be made by taking a plastic bottle, drilling a hole through its lid and inserting a plastic tube, which is bent at one end. Seal the tube on the lid with glue to hold it steady.
