Datasheets
Download:Pall’s UltiKleen Excellar filter is constructed of the most technologically advanced non-dewetting all-fluoro-polymer media that we offer to the semiconductor industry. This filter is specifically designed to handle the aqueous-based gas-generating chemicals vital for wafer cleaning (SC-1, SC-2, and SPM).
The non-dewetting property of the UltiKleen Excellar filter is achieved using our proprietary MST (Molecular Surface Tailoring) technology to tailor the surface chemistry on a molecular scale. This method is unlike conventional coating-and grafting-based methods that can compromise chemical compatibility and purity. The advantage of MST is that the PTFE membrane remains robust and durable in highly corrosive acids, bases, and organic compounds.
