The 125mL wide-mouth ultra-clean PE bottle uses a dual-layer HDPE structure, and the brown body offers good light blocking against light-induced chemical degradation. The wide mouth eases filling of powders and high-viscosity chemicals and makes cleaning the inner wall easier. Produced in a strictly controlled dust-free environment, it minimises ion leaching and particle release, preserving the purity of the stored medium. Suited to dispensing and storage of semiconductor wet chemicals and high-purity reagents, with custom exterior colours available — meeting clean storage and transport needs in laboratories and precision electronic chemicals.
