The large-capacity dual-layer HDPE body has solid wall thickness and pairs with a PTFE corrosion-resistant sealing gasket to block air and moisture, resisting leakage in long-term storage. Formed and washed entirely in a cleanroom with strict particle and metal leaching standards, it keeps high-purity electronic liquids and reagents free from interference. The pigmented outer resin safely stores photosensitive photolithography consumables. The capacity suits batch sample retention and production line dispensing and transfer, the bottle is stable to hold, and custom exterior colours are available on request.
