The 19L stainless steel drum is built for medium-capacity material transfer on semiconductor pilot and mass production lines. The 304 body is light and effortless to handle. Complete acid pickling and passivation leaves no free metal impurities on the surface, preventing contamination of photoresists and electronic solvents. The brushed matte outer surface does not easily retain dust, making routine cleanroom disinfection easier. A single integrated grip paired with a narrow-aperture sealed structure blocks light and slows material degradation — covering dispensing, temporary storage and short-distance transfer, it suits the storage of various high-purity chemical media in the microelectronics industry.
