The 200L composite PAIL drum features dual large and small openings, balancing rapid filling with sealed sampling and flow guidance for automated loading operations. The outer steel drum provides high-strength protection, while the inner ultra-clean liner system keeps container impurities from contaminating high-purity materials. Production follows clean-control standards throughout, effectively controlling particle and metal ion leaching. The sturdy, impact-resistant body suits long-distance transport and is widely used for storing and transporting semiconductor high-purity chemicals. Exterior colours can be customised, fitting industrial batch production processes.
