SupaPore VPBA
SupaPore VPBA cartridges use a high flow, highly Asymmetric hydrophillic PES membrane. The VPBA contains a built in pre-filter. The supporting pre-filter layer and membrane combination improves on steam life and dirt holding capacity making the VPBA cartridge an ideal choice for the Pharmaceutical Industry where challenging or heavily loaded solutions are to be processed.
The SupaPore VPBA has proven successful in API or Pharmaceutical manufacturing, where contamination levels are known to be higher, or where a double layer membrane is required, or bioburden control is critical to successful filtration. The dual layer construction of the SupaPore VPBA improves wetting for integrity testing and reduces the risk of false failure. This additional membrane layer holds the water used to wet the filter against the final layer, therefore achieving more effective wetting.
The VPBA grade cartridge is ideal for final sterilising or bioburden reduction applications, the high flow capacity is achieved with extremely low differential pressure.
All cartridges are thermally bonded and adhesive free. Each unit is pre-flushed with ultra-pure water and integrity tested before final assembly.
