Product Description

Hardened aerospace grade stainless steel is used to produce all of NATIONAL's die sets. The 3mm to 19mm dies are used primarily for KBr pellets for transmission analysis by IR spectroscopy, while the larger dies are most commonly used for producing briquettes for XRF spectroscopy. The 13mm Macro-Micro die is chosen by most spectroscopists for KBr pellets, and it is available with paper inserts with a variety of small apertures (1.5, 3, 5, & 11mm) that enable the user to make micro-pellets with a 13mm die set and also provide a useful frame for mounting and storing the pellets.

All NATIONAL dies have an upper and lower stainless steel section for ease of disassembly and they are sealed with viton seals. For ease of use, the weight was reduced in all die sets in the 13mm to 40mm range by adding an outer shield of aluminum. This feature makes them much easier to handle than 2 piece dies made completely from stainless steel due to their lighter weight, but without sacrificing strength or durability. The dies can be evacuated with a vacuum pump to reduce the moisture in the sample. 13mm and 20mm dies are typically used with 12 to 20 ton presses, while the larger size dies are used with 20 to 40 ton presses and are most commonly used for briquetting samples for XRF analysis.

High-Precision Pellet Formation

These pellet dies deliver outstanding uniformity and consistency in pellet thickness and diameter, thanks to meticulous engineering and tight manufacturing tolerances. Their compatibility with industry-standard hydraulic or mechanical presses ensures reliable pelletizing for FTIR, IR, XRF, and other analytical techniques. The robust construction allows for repeated use under high pressures, up to 15 tons, without loss of accuracy.

Flexible and User-Friendly Design

The fully disassemblable structure of the die sets greatly simplifies cleaning and maintenance, reducing downtime between sample preparations. Standard models accommodate up to 13 mm diameter pellets, but customization is available to meet varied laboratory needs. The manual operation mode grants users precise control during pressing, maximizing flexibility and efficiency for both routine and advanced analyses.

FAQs of Evacuable KBr & Briquetting Pellet Dies:

Q: How should the Evacuable KBr & Briquetting Pellet Dies be cleaned and maintained?

A: Each die set is fully disassemblable, allowing users to easily take apart the components for thorough cleaning. After each use, carefully disassemble the die, clean the surfaces with a suitable solvent or soft brush to remove residue, and dry all components before reassembly.

Q: What types of presses are compatible with these pellet die sets?

A: These dies are designed for manual operation and are compatible with both hydraulic and mechanical laboratory presses. Ensure the press can generate pressures up to 15 tons, depending on the die model and required application.

Q: When is it recommended to use these pellet dies in the laboratory?

A: Use these dies when preparing samples for FTIR, IR, XRF, or other spectroscopic analyses that require precise and uniform pellets. They are suitable for applications demanding high reproducibility and purity in the sample matrix.

Q: Where can custom-sized pellet dies be procured?

A: Custom-sized pellet dies can be ordered directly from the manufacturer or authorized distributors. While the standard model produces up to 13 mm diameter pellets, other sizes are available on request to match specific laboratory needs.

Q: What is the process for forming pellets with these die sets?

A: Begin by loading your powdered sample into the die cavity. Assemble the die, apply pressure using a compatible press (hydraulic or mechanical), and maintain the pressure as required for your method. After pressing, disassemble the die to retrieve the finished pellet.

Q: What are the benefits of using an evacuable briquetting pellet die for sample preparation?

A: These dies ensure high pellet uniformity, minimum contamination, and compatibility with vacuum applications, enhancing spectral clarity and analytical accuracy. Full disassemblability reduces cross-sample contamination risks and simplifies maintenance.
