The 200L ultra-clean dual-layer PE drum (580 model) has an optimised outer diameter for excellent space compatibility, matching mainstream warehouse racking and transfer equipment. The dual-layer PE one-piece structure effectively blocks impurity leaching. A fully dust-free production process strictly controls particle and metal ion leaching, preserving the original quality of high-purity wet chemicals. The impact-resistant body suits long-distance logistics and multi-layer stacking, and the clean grey base finish supports colour customisation — suited to large-scale storage and transport of bulk high-purity reagents in the semiconductor industry.
