Core Application Fields
Environmental Monitoring
Soil/sewage heavy metal digestion (Pb, Cd trace analysis).Food Safety
Toxic element detection in food (Hg, As FDA-compliant analysis).Biomedicine
Tissue sample pretreatment (compatible with HF acid digestion of bone tissue).Semiconductor Industry
Ultra-pure reagent preparation (eliminates metal ion contamination).
Performance Advantages
- Traditional Material Replacement:
Superior to glass (HF acid intolerance) and quartz (high-pressure fragility), with 3x longer lifespan. - Cost Efficiency:
Reusable **>100 times**, reducing per-test costs. - Automation Compatibility:
Supports high-throughput digestion racks (e.g., 96-well design), enhancing lab efficiency.
Selection Guidelines
- Ultra-High Pressure/HF Acid Systems → Prioritize TFM-modified PTFE tubes (pressure resistance >100 bar).
- Transparency Requirements → Choose PFA semi-transparent tubes (pressure resistance <60 bar).
- Routine Digestion → Standard PTFE tubes (optimal cost-effectiveness).
Note: PTFE digestion tube-cap assemblies, with their "secure sealing + ultra-low background" properties, represent the global gold standard for elemental analysis pretreatment.
Translation adheres strictly to technical terminology and industry conventions (e.g., "trace analysis," "FDA-compliant," "ultra-pure reagents"). Pressure units (bar) and material designations (TFM/PFA) retain original specifications.
