“Cowbell” distilling flask, also known as a fractional distillation flask or fractioning flask, is a vessel with a round bottom and a long neck from which a side arm protrudes. It is primarily used for distillation, the process of separating a mixture of liquids with different boiling points through evaporation and condensation.

“Cowbell” dropping funnel is a glassware used to transfer fluids. They are fitted with a stopcock which allows the flow to be controlled. Dropping funnels are useful for adding reagents slowly, i.e. drop-wise. This may be desirable when the quick addition of the reagent may result in side reactions, or if the reaction is too vigorous.

“Cowbell” Filtering flasks are usually used with some sort of vacuum assembly. The most economical is an aspirator that connects to the kitchen tap. A filter flask can also be used with different types of funnels such thistle tubes, buchner funnels and the like. Filter flasks are used to speed up filtration by connecting a vacuum aspirator to a water tap.

Ground glass joints are used in laboratories to quickly and easily fit leak-tight apparatus together from commonly available parts. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or rubber bungs and glass tubes as joints, which took time to prepare as well.

The apparatus is usually made of glass, or sometimes of polyethylene, and consists of three vertically stacked chambers, roughly resembling a snowman The prepared gas is usually impure, contaminated with fine aerosol of the reagents and water vapor. The gases may need to be filtered, washed and dried before further use.
