A PFA immersion supply tube dedicated to 60L matching liner bags. The perfluorinated material withstands highly corrosive electronic chemicals without leaching metal impurities or generating fine particles that would contaminate photoresists and high-purity solvents. Subject to strict cleanliness control before dispatch, it suits automated sealed feeding systems. The end-of-tube extraction design draws media from the drum thoroughly, reducing residual waste. Formed in one piece with no seams or dead corners, it resists chemical adsorption and caking and is easy to fit and remove. Paired with a liner bag it enables cross-contamination-free changeover — suited to continuous delivery of high-purity chemicals on dust-free wafer production lines.
