The 6L small pressure-resistant steel drum is built for storing and delivering semiconductor metal precursors. Formed in one piece from thickened 316L stainless steel, the acid-pickled and passivated inner wall prevents metal impurity leaching while the mirror-polished outer wall stays clean and easy to wipe down. Suited to an extremely wide temperature range with ample pressure safety margin, the top integrates a dual pressure-regulating valve set for precise, sealed, contact-free feeding. A protective bracket aids laboratory transfer, isolating air and moisture throughout to prevent sensitive precursors from oxidising — a dedicated sealed storage container for R&D and small-batch thin-film deposition processes.
