This 316L stainless steel high-purity pressure vessel is built for high-viscosity liquid precursor applications, suited to storing and delivering ultra-high-purity semiconductor media. A passivated inner wall minimises metal ion leaching, supporting purity of up to 9N5. The mirror-polished outer wall makes cleanroom cleaning and disinfection easier, and a multi-port layout suits pipeline connection. Structurally solid and reliable, it protects the intrinsic properties of high-purity chemicals down to the finest process detail, meeting demanding semiconductor fabrication requirements.
