PFA (Perfluoroalkoxy resin) syringes feature excellent chemical resistance, thermal stability, and high purity. They are indispensable consumables in modern analytical techniques and microelectronics processes.
I. Characteristics of PFA Syringes
1. Resistant to strong acids, alkalis, and organic solvents, and do not react with chemical reagents, ensuring sample purity.
2. Low content of metal element impurities. Strict pollution control is implemented during the production process to avoid introducing metal impurities, making them suitable for ultra-pure experiments (such as semiconductor and trace analysis).
3. Resistant to high and low temperatures (-200℃ to +260℃), can be sterilized at high temperature, or used in conditions such as liquid nitrogen, with good anti-deformation and recoverability.
4. Smooth surface, not easy to adhere to samples, reducing residue, easy to clean, and can be reused multiple times.
5. High transparency, with scales, facilitating the observation of the liquid state.
II. Applications of PFA Syringes
1. High-purity reagent handling: Transfer ultra-pure acids, alkalis, and organic solvents to avoid metal contamination (such as sample pre-treatment for ICP-MS and LC-MS).
2. Handling of highly corrosive liquids: Precise transfer of dangerous reagents such as highly corrosive liquids.
3. High-temperature/low-temperature experiments: Sampling in high-temperature reactions and preservation of low-temperature biological samples (such as in liquid nitrogen environment).
4. Semiconductor and photovoltaic industries: Distribution of high-purity chemicals in wet processes to prevent contamination of silicon wafers, etc.
III. Advantages Compared with Other Materials
1. vs Glass Syringes: Resistant to hydrofluoric acid, not easy to break, suitable for field or dangerous environments.
2. vs PP/PE Syringes: Stronger solvent resistance, no risk of dissolution.
3. vs PTFE Syringes: Higher mechanical strength and transparency.
