Dispensers designed to store and deliver measured amounts of material. These dispensers consist of a container that pours out the material into trays, vessels, microplates, or centrifuges, without human contact with the sample. Laboratory dispensers may be operated manually, automatically timed or computer controlled for more complicated projects. These dispensers are used instead of simply pouring out materials because they are more accurate, help to cut down on waste and lessen the risk of sample contamination. Dedicated dispensers for laboratory liquids, laboratory slides, and antibiotic sensitivity disks are available. They are commonly used in clinical and pharmaceutical laboratories.
