Notable experiments

The wash bottle is generally used in the clean-up phase of many experiments |
A wash bottle is a squeeze bottle with a nozzle, usually used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.
Most wash bottles are made up of polyethylene, which is a petroleum based plastic.
Usually, wash bottles are filled with deionized water. Wash bottles may also be filled with detergent solutions and rinse solvents such as acetone and ethanol.
When pressure is applied to the bottle, the water inside becomes pressurized and as a result it is forced out the nozzle into a narrow stream of liquid.
