PFA sample vials are designed for sample digestion in geological, nuclear, environmental, food, semiconductor, and trace analysis applications. 1. They exhibit excellent chemical resistance, tolerating strong acids, strong bases, and organic solvents, especially in fluorine-containing systems. 2. Due to extremely low leaching and very low levels of metallic impurities (e.g., Pb, U < 0.01 ppb), they maintain sample purity. 3. They can withstand temperatures from -200°C to +260°C and feature a threaded cap for a secure seal. 4. The translucent vial body allows for easy observation, and the smooth inner wall facilitates cleaning. 5. Available in V-shaped, U-shaped, and flat-bottom designs to meet various experimental needs and are compatible with heated plates, modular digesters, and microwave digestion systems.
