Optimized for laboratory operations
The HERZOG pellet press HTP offers the full benefits of program-controlled sample preparation for x-ray fluorescence analysis. Pelletizing with the HERZOG HTP significantly increases reproducibility and accuracy of sample preparation. The HTP pellet press is a high-quality, precision engineering product with compact dimensions. It is ideally suited for laboratory requirements.

Optimum quality of pressed pellets
The HERZOG hydraulic HTP press produces high-quality pressed pellets with a mirrorlike surface necessary for optimal XRF results. The HSM achieves the desired homogeneity and stability of each individual pellet with a maximum of reproducibility. The HTP 40 reaches press forces of 400 kN, the HTP 60 of up to 600 kN even with larger sample diameters.

Easy handlingA swing-out cross-head makes filling and cleaning of the die quick, simple and safe. A number of pressing variables can be selected, depending on the press tool employed. Precision press tools with a range of diameters and materials permit free pressing, pressing in aluminum shells, and pressing in steel rings.

Precise control of the pelletizing process
The pelletizing process of the HTP is controlled by the PLC program. This leads to substantial improvement in reproducibility of sample preparation and consequently more precise analysis results. Pelletizing parameters such as total pressing force, incremental increase and decrease of pressure as well as pressure holding time can be preset on the HMI panel. The pressure increase and decrease during pelletizing are controlled to reduce inner stresses within the sample. This allows the production of perfect pellets even with complicated sample material.
