PTFE Digestion and Reaction Tubes
A$100.00
Designed for the most demanding analytical procedures, Bauer and Klein PTFE (Polytetrafluoroethylene) Digestion Tubes are engineered for critical sample preparation workflows requiring extreme purity and chemical inertness. These tubes solve the common challenges of trace analysis—background contamination and vessel corrosion—by providing an unparalleled non-reactive environment.
These vessels are indispensable for applications involving strong mineral acids at elevated temperatures, such as Environmental Testing (soil, water), Geology/Mineralogy, and Pharmaceutical Trace Metal analysis (ICP-MS/ICP-OES).
Key Performance Features
Exceptional Chemical Compatibility: Fabricated from high-purity, virgin PTFE, these tubes are impervious to aggressive chemical attacks. They safely contain concentrated nitric ($HNO_3$), hydrochloric ($HCl$), sulfuric ($H_2SO_4$), and critically, hydrofluoric ($HF$) acids, which decompose standard glassware.
High-Temperature Stability: Our PTFE formulation maintains structural integrity and chemical inertness at sustained temperatures up to 260°C (500°F), making them suitable for intense hot plate digestion and high-pressure microwave digestion protocols.
Ultra-Low Leachable Profile: The non-porous, hydrophobic surface minimizes analyte adsorption and prevents leaching of trace contaminants, ensuring the accuracy of ultra-trace elemental quantification (ppb and ppt levels).
Superior Durability: Unlike fragile quartz or glass, Bauer and Klein PTFE tubes are extremely robust, resilient to thermal shock, and resistant to cracking or shattering, ensuring long-term laboratory safety and cost-effectiveness.
Versatile Design: The conical or flat-bottom designs resemble high-performance centrifuge tubes, allowing for seamless integration into various block digestion systems and handling protocols.
Applications
Sample digestion for ICP-MS and ICP-OES trace element analysis.
Dissolution of geological or mineral samples.
Preparation of organic samples (food, polymer, tissue).
General chemical synthesis and reactions involving corrosive reagents.
Custom Fabrication Capabilities
