Product Description
Evacuable Pellet Dies
Atlas Series Evacuable Pellet Dies suitable compacting powdered samples into discs or briquettes. These are particularly well suited for the preparation of solid KBr pellets for FTIR molecular spectroscopic analysis and XRF pellets for X-Ray Fluorescence atomic spectroscopic analysis (as required by a number of USLP and ASTM methods), but also find use in a broad range of other applications. Atlas Series Evacuable Pellet Dies are typically used in conjunction with the Specacs Atlas Series of Hydraulic Press Products.
These Evacuable Pellet Dies produce circular pellets in sizes from 5 mm to 40 mm diameter as standard, but other shapes and sizes are available on request. These pellet dies cover a range of load capabilities. For optimum quality and durability of the pellet die, all parts are manufactured from hardened stainless steel, and surfaces that come in contact with the sample are highly polished. Each Pellet Die comprises an evacuable base, body, plunger, set of pellets, extractor ring, and O Ring Kit.

Wide range of sizes and load capabilities
Superior Sealing and Vacuum RetentionEquipped with O-ring sealing, the Evacuable Pellet Die maintains reliable vacuum retention during pellet pressing, significantly improving sample quality and consistency. The evacuable design allows for easy moisture and air removal, essential for sensitive analytical procedures such as FTIR and XRF.
Mirror Polished and Precision EngineeredAll internal surfaces are mirror polished to facilitate effortless pellet removal and ensure uniformity. High-precision machining techniques guarantee reproducible pellet formation, making the die ideal for rigorous laboratory protocols where accuracy is paramount.
Built for Durability and VersatilityManufactured from corrosion-resistant stainless steel, each die is built to withstand daily laboratory use and high pressures, up to 25 tons. This reusability, coupled with a comprehensive accessory kit and availability in multiple sizes, makes it a versatile choice for research environments.
FAQs of Evacuable Pellet Dies:
Q: How do I use the Evacuable Pellet Die for laboratory sample preparation?
A: To use the Evacuable Pellet Die, insert your powder, tablet, or fine-grained sample into the die cavity, place the spacers as needed, and assemble the plunger and base. Connect the vacuum port via the standard hose nipple (6 mm) and evacuate air to create a moisture-free environment. Apply pressure (up to 25 tons) using a manual hydraulic press. Once complete, use the ejector for smooth pellet removal.
Q: What types of samples can be processed with this pellet die?
A: The die is suitable for a wide range of laboratory samples, including powders, tablets, and fine-grained substances, making it ideal for preparing samples for FTIR, XRF, and pellet press applications in fields such as chemistry, geology, and materials science.
Q: When should I apply the vacuum during pellet pressing?
A: The vacuum should be applied before exerting pressure with the hydraulic press. This step removes air and moisture from the sample, leading to high-quality, consistent pellets necessary for accurate analytical results.
Q: Where can the Evacuable Pellet Die be used?
A: This equipment is designed primarily for laboratory environments. Its most commonly used in research labs, quality control facilities, and academic institutions for sample preparation in analytical applications requiring pellet formation.
Q: What is the process for cleaning and maintaining the die?
A: After each use, disassemble the die and clean all components with the provided cleaning kit. Ensure all residues are removed, and the mirror-polished surfaces are free from contaminants to maintain optimal performance and prolong the tools longevity.
Q: What benefits does the stainless steel construction provide?
A: The high-grade stainless steel construction delivers excellent corrosion resistance, high pressure tolerance, and long-term durability, allowing repeated use without compromising performance, even when processing challenging or reactive materials.
