A laboratory press is used to create compressed pellets out of powdered material for use in applications as diverse as pharmaceutical development, spectroscopy, and bomb calorimetry. Powders are placed into a die (or mold) of the laboratory press and are pressed into shape by hydraulic action. A laboratory press can have a wide range of pressures, from 15 to 40 metric tons. One important consideration is the shape of the desired pellets, which can vary between different products. Some laboratory presses can accommodate a wide range of different-sized or customized dies. Though most laboratory presses are hydraulic, other laboratory presses can be of a screw press configuration.
