The 1L wide-mouth ultra-clean PE bottle uses a dual-layer HDPE structure, and the thickened body improves overall structural stability, better suited to long-term storage and transport of medium-to-large reagent volumes. The brown body offers good light blocking, effectively protecting photosensitive high-purity chemicals. The generous wide mouth eases filling of large volumes and cleaning of the inner wall. Produced dust-free throughout with effective particle and ion leaching control, it protects media purity — widely used for semiconductor wet electronic chemicals and premium research reagent storage, with custom bottle colours available.
