Customized PTFE Sand Core Filtration Device, Corrosion and Organic Solvent Resistant.

Characteristics of PFA Büchner Funnel + PFA Filter Flask

1. Excellent Chemical Stability

PFA material exhibits extremely high chemical inertness, capable of withstanding corrosive media such as strong acids, strong bases, and organic solvents (e.g., aqua regia, HF), ensuring long-term use in complex chemical environments without corrosion or sample contamination.

2. Broad Temperature Range

PFA material maintains stable performance within a temperature range of -200°C to +260°C, making it suitable for experimental operations under extreme temperature conditions, such as high-temperature steam or low-temperature freezing environments.

3. High Purity and Low Contamination

PFA material has an extremely low background value, with metal element content (e.g., lead, uranium) less than 0.01 ppb, and minimal leaching and migration, ensuring no sample contamination. It is particularly suitable for trace analysis and ultra-pure experiments.

4. Transparency and Easy Cleaning

PFA Büchner funnels and filter flasks are typically transparent, facilitating observation of the experimental process. Their smooth surfaces resist residue buildup, are easy to clean, and can be reused.

5. Wear Resistance and Long Lifespan

PFA material features a low friction coefficient and self-lubricating properties, offering excellent wear resistance. This extends the equipment's service life and reduces maintenance costs.

6. Wide Applicability

This combination is suitable for various fields, including chemical analysis, pharmaceutical industry, biological products, petrochemicals, and environmental monitoring. It effectively separates and purifies samples while minimizing interference from contaminants.

7. Customization and Versatility

PFA Büchner funnels and filter flasks support custom processing, allowing adjustments in size and functionality (e.g., adding scales) to meet the needs of different experimental scenarios.
