Press techology
Press technology:

Pressing Technology, due to the rapid preparation of pellets, has been used in quality control. This method works well when analyzing samples containing large amounts of volatile components.

We offer the original press from HD Elektronik and PD Instruments.

The dies are designed for use with our hydraulic presses.

Halide disks for infrared analysis are usually produced with 13 mm sized dies.

The larger sized dies with 32 and 40 mm are commonly used in pressing samples for XRF and XRD analysis and many other industrial applications. Nevertheless we can produce dies with diameters between

8 and 55 mm. All of the dies are equipped with nitrile O-ring seals and 2 pellets between the sample can be pressed.


In our offer we also have a matrix that allows compression of the rings.


In most cases, a binder is required for the preparation of pressed pellets for XRF.

Sample and binder must be mixed homogeneously. We recommends their automatic mixer (MU-K-Mixer)

Alu capse

Alu cups are used to stabilize your sample from 2 sides. However, for a successful use, the sample must show at least some binding properties. Another advantage of this method is the possibility of labeling and sucking with autosamplers.

  • labeled molds, which do not obstructs the sample surface
  • designed for use with autosampler
