A typical chem lab involves reactions that create very fine particles that must be separated from a solution. The gooch crucible contains a very fine, glass filter to trap those particles. The rubber crucible holder provides a seal between the crucible and the collection flask for the waste solution. The aspirator connects to the sink faucet and uses Bernoulli’s principle to generate low pressure through connecting to the filter flask that sits beneath the crucible. A typical experiment using this equipment is determining the percentage of silver in a "silver" dime. Dissolving the metal in nitric acid, then turning the silver atoms into small particles of solid silver chloride that are caught by the vacuum filtration system, makes up this lab.
