Funnels assist with the easy transference of liquids or powders into containers. Typically with a wide mouth that feeds substances through the narrow stem, these devices prevent unwanted spills and maintain a clean work space. The funnels are available in specialized styles for specific laboratory applications. Many styles are compatible with filter paper or a glass frit for filtration. With the ability to channel any fine-grain or fluid material, funnels are essential tools for any environment.
