Custom High Purity PTFE Microwave Digestion Vessels and Graphite Block Compatible Acid Evaporation Tanks for Trace Metal Analysis

Product Overview

This high-performance sample preparation system is engineered for laboratories requiring the highest levels of chemical purity and thermal stability. These digestion vessels are specifically designed to facilitate the complete decomposition of complex matrices, such as soil, minerals, and organic tissues, within both microwave digestion systems and automated graphite digestion blocks. By utilizing premium-grade polytetrafluoroethylene (PTFE), the equipment provides a near-zero background level of trace metals, making it an essential component for facilities performing ICP-OES and ICP-MS analysis.

The versatility of this unit allows it to function as a seamless bridge between high-pressure microwave digestion and subsequent acid evaporation (acid removal) processes. Whether integrated into a 44-position graphite block or used as a standalone high-pressure liner, the system ensures consistent volumetric heating and structural integrity. Industries ranging from environmental monitoring and food safety to geochemistry and pharmaceutical research rely on this equipment to maintain the volatile element retention and prevent cross-contamination during aggressive acid treatments.

Built to withstand the rigorous demands of industrial laboratory environments, the unit offers unparalleled resistance to concentrated nitric acid, hydrofluoric acid, and aqua regia. Every vessel is manufactured with precision to ensure a perfect fit with existing laboratory infrastructure, providing procurement teams and lab managers with a reliable, long-term solution for high-throughput sample preparation. This system represents the pinnacle of fluoropolymer engineering, delivering the robustness needed for high-temperature and high-pressure chemical reactions.

Key Features

• High-Purity PTFE Construction: Manufactured from premium, virgin fluoropolymer materials, this equipment ensures extremely low background levels for trace elements like selenium, molybdenum, and heavy metals, crucial for high-sensitivity analytical results.
• Microwave-Transparent Properties: The material is inherently microwave-transparent, allowing for rapid and uniform volumetric heating of sample-acid mixtures, which significantly reduces digestion times compared to traditional conductive heating.
• Exceptional Chemical Inertness: This system remains unaffected by the strongest oxidizing acids and solvents, including HF and HClO4, preventing corrosion and ensuring the vessel does not introduce metallic impurities into the sample.
• Superior Thermal Stability: Designed to operate reliably at elevated temperatures, the unit maintains its structural integrity and sealing performance, facilitating the complete decomposition of difficult soil and mineral matrices.
• Bespoke CNC Fabrication: Every vessel can be customized via precision CNC machining to meet specific laboratory dimensions, ensuring compatibility with various microwave rotors and graphite heating blocks.
• Advanced Sealing Integrity: The precision-engineered caps and liners support high internal pressures, often required for pressurized microwave digestion, preventing the escape of volatile analytes and ensuring operator safety.
• Optimized for Acid Evaporation: The geometry and material properties are specifically tailored for efficient acid removal (赶酸) processes, allowing for smooth transitions from digestion to final sample dilution.
• High-Throughput Configuration: Available in 44-position layouts and other high-density formats, the equipment is designed to maximize laboratory efficiency and sample turnaround times without compromising on results.
