A hydraulic press can have many applications. Usually, a laboratory hydraulic press will be used to prepare samples for analysis by compressing them into pellets or thin films. The particles are forced together, creating a homogenous sample ideal for spectroscopic examination.

The Manual & Automatic Hydraulic Press the user applies pressure by hand & switch, using a handle by manual and switch for automatic to pump pressure into the hydraulic fluid system. This pressure is transferred to a secondary area and the resulting force can be as great as 25 tons.

FTIR spectroscopy is an example of an analytical technique that uses samples prepared by a hydraulic press. KBr (potassium bromide) is often mixed with ground samples and compressed into pellets, which are then used for Infrared spectroscopic analysis. Suitable powder mixtures can also be compressed to form pellets in a similar way for determination of their compositional makeup.

Milled or finely ground, powdered samples are placed inside a ‘pellet die’. This is a durable container for the sample in which a die with sample is placed within the press. As the die is compressed within the hydraulic press, an internal plunger for the die assembly is forced against the contained sample within.
