Constantly increasing process demands in the Biopharmacuetical industry has driven Pall Corporation to develop the new Supradisc II depth filter modules. The Supradisc II design combines the filtration performance of Seitz media and the structural robustness of interlocking dual drainage plates. This provides the most robust design available in the market today.
The dual drainage plate design of the Supradisc II modules optimizes the flow distribution by providing unobstructed process flow. These advancements in module design also enhance module integrity as well as superior resistance to back pressure failures of the filter media.

Pall Supradisc II features
• Highest structural robustness due to dual drainage plates.
  - Interlocking and welded drainage
plates provide similar structural integrity as found with most filter cartridge cage and core assemblies.
• Optimized flow distribution upstream and downstream of the filter sheets maximizes filter utilization.
  - Filter media is less susceptible to blinding from media to media contact within the module assembly.
  - Unobstructed process flow.
• Fully supported filter sheets inhibit the rupturing of filter media frequently associated with back pressure.
• Shipping and handling damage is significantly reduced through the very same interlocking and welded drainage plates.
• Highest packing density minimizes hold up volume.
• Supradisc II modules are steam sterilizable at 125 °C (257 °F) for 30 minutes.
• All plastic components used in construction meet the specifications for the biological test listed in the current version of the USP Class VI 121 °C.
• Supradisc II modules and all their components are fully traceable by serial number.
The filter sheets meet the specifications set forth in the US Code of Federal Regulations Title 21, parts 177.2260 e, f, g, h, i, j, k, l. The materials for all plastic components are listed in US Code of Federal Regulations Title 21, part 177.1520.
With regard to food law conformity, the manufacture of depth filter sheets is also subject to ongoing analysis by the German ISEGA Forschungs- und Untersuchungsgesellschaft mbH, Aschaffenburg.
