Purpose-built for highly photosensitive electronic chemicals such as photoresists. The thickened 304 body has a passivated inner wall that effectively blocks metal ion leaching and prevents photoresists from degrading through light exposure. The brushed outer surface resists wear and scratches and produces little dust or debris during cleanroom transfer. A narrow-aperture sealed structure blocks light and air, delaying photoresist deterioration, while dual side handles make manual transfer and dispensing easier. Light in weight yet generous in capacity, it can be paired with liner bags to prevent cross-contamination — suited to the full workflow of photoresist production, dispensing and wafer-fab transfer.
