What is a Hydraulic Press?

A hydraulic press uses a hydraulic cylinder to produce a compressive force. Within a hydraulic press, there is a plate where the sample is placed to be pressed for sample preparation. This blog post will outline the working principle of a hydraulic press and will touch on the hydraulic presses available from XRF Scientific.

Working Principle of a Hydraulic Press

A hydraulic press works on the principle of Pascal’s law, which states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. Within the hydraulic press, there is a piston that works as a pump, that provides a modest mechanical force to a small area of the sample. There is also a piston with a larger area, which produces a larger mechanical force.

Hydraulic Press Advantages

There are a variety of advantages for using hydraulic presses, specifically for XRF sample preparation.

The use of hydraulic presses has considerably increased the speed at which XRF sample preparation can be performed. This is evident in hand-fed hydraulic presses, where the ease and speed of sample switching is considerably improved.

These instruments are also extremely beneficial for high-volume sample preparation, also increasing the speed of sampling.

Hydraulic presses are versatile instruments and they can be used to prepare a large range of different samples for XRF. There is also a lot of flexibility in operation, with various speeds, forces, directions, and pressure available.

Hydraulic Presses from XRF Scientific

XRF Scientific supply a range of laboratory equipment including hydraulic presses for XRF sample preparation.

Our hydraulic presses are available in a range of configurations, including automatic, manual, power, and motorized.

The automatic hydraulic presses are power-assisted, programmable, and microprocessor controlled. They are available in load capacities of 8 – 40 tons for a wide range of applications.

Our manual hydraulic press is a hand press, suitable for preparing powder samples for XRF. It includes an accurate pressure gauge and has tough housing.

The motorized hydraulic press is power-assisted and can operate up to 25 tons. The pressure of this instrument can be directly set, and it is fully compatible with our dies.

Our power hydraulic presses operate from 8 to 25 tons and they are designed for a range of pressing applications, including XRF sample preparation.
