PRODUCT INTRODUCTION
Our PTFE crucibles are crafted from premium laboratory-grade PTFE material, engineered specifically for harsh chemical digestion and precise trace analysis. Featuring exceptional chemical inertness, high temperature tolerance, and non-stick properties, this crucible ensures maximum sample purity and zero contamination during testing. It is an indispensable tool for chemical, environmental, semiconductor, and academic research laboratories.
CORE FEATURES
• Excellent Chemical Inertness Resists strong acids, alkalis, aqua regia, hydrofluoric acid (HF), and organic solvents.
• Ultra-Low Blank Value Prevents metal ion precipitation, making it ideal for ICP-MS and AAS trace element analysis.
• High & Low Temperature Tolerance Performs reliably within a temperature range of -200°C to +250°C.
• Non-Sticking & Easy Cleaning Smooth inner wall prevents sample retention, ensuring maximum liquid recovery and quick cleaning.
• Structural Stability Uniform wall thickness and reinforced base prevent deformation during heating and placement.
