Extractors are tools or devices designed to remove specific substances from a mixture or environment. They are commonly used in various industries, including food processing, pharmaceuticals, and environmental science. For example, in the culinary world, an oil extractor can separate essential oils from herbs, while in laboratories, solvent extractors are used to isolate compounds from samples. In addition to industrial applications, extractors can also refer to software programs that gather data from websites or databases. These data extractors help users collect and organize information efficiently, making it easier to analyze and utilize for research or business purposes.
