UltiKleen™ G2 Excellar ERL Filter and KC Assemblies

UltiKleen G2 Excellar ERL Filter

The enhanced retention (ER) and improved nondewetting properties of the UltiKleen G2 Excellar ERL filter have enabled semiconductor makers to meet the critical chemical process filtration requirements beyond the 45 nanometers (nm) manufacturing node. Designed for critical single-pass point-of-use filtration, the filter’s high flow rate also makes it suitable for recirculation bath applications.

An advanced media support design maximizes the effective filter area of the cartridge. The larger filter area increases dirt-holding capacity, thereby extending service life. The liquid flow rate of the UltiKleen G2 Excellar ERL filter is more than 30% higher than that of the standard UltiKleen Excellar ER filter.

The UltiKleen G2 Excellar ERL filter medium is made using Pall’s proprietary Molecular Surface Tailoring (MST) technology. MST imparts nondewetting properties to the PTFE membrane without adding a chemical layer to the surface of the medium. A hyperfine pore matrix inside the membrane provides significantly improved retention of particles down to 15 nm. The result is a robust, reliable and chemically clean filter suitable for use in aggressive high-temperature cleaning chemistries, including aqueous chemistries such as hot SPM, SC-1 and SC-2.

  • Enhanced retention of particles
  • Robust nondewetting PTFE medium
  • High flow rates
  • Hyperfine porous media matrix design
  • All ultra-high-purity fluoro-polymer construction
  • Provided prewet, with Full-fill1ultrapure water package (standard)
  • Low extractables (Single digit ppb 2 in a 5% HCL extraction of 1.5 liters for 24 hours)
  • 100% integrity tested

UltiKleen G2 Excellar ERL KC Assemblies

The Pall UltiKleen G2 KC assemblies, which are made of high-purity PFA, are completely disposable filter units that contain UltiKleen Excellar ERL cartridges. They are specifically designed and ideally suited for high-temperature process chemicals, particularly mixtures of sulfuric acid and hydrogen peroxide (SPM). The unique downstream venting-type assemblies allow bubbles to exhaust from chemicals efficiently and provide higher particle cleanliness levels.

  • Downstream venting available
  • Disposable filter unit with filter cartridge integrally sealed in housing
  • Sealed assembly for safer handling and faster changeout
1 Package is completely filled with ultrapure water.
2 Total metal concentrations in 13 elements: Li, Na, Mg, Al, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Pb.
