A wash bottle is a squeeze bottle with a nozzle which is used to rinse various pieces of laboratory glassware like test tubes and round bottom flasks. Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid. They are generally made of low-density polyethylene (LDPE). Wash bottles may be filled with a range of common laboratory solvents and reagents, according to the work to be undertaken, for example, deionized water, detergent solutions and rinse solvents such as acetone, isopropanol or ethanol. There are a consistent set of colour codes and markings used to identify the contents of wash bottles. Red is used for acetone, White for ethanol or sodium hypochlorite, green for methanol, yellow for isopropanol and blue for distilled water. In biological labs it is common to keep sodium hypochlorite solution in a wash bottle to disinfect unneeded cultures. Wash bottles help users control and measure the precise amount of liquid used and also, unwanted substances or particles cannot pass through wash bottles. For such cases, the use of wash bottles is more convenient than using beaker and graduated cylinders.
