AseptiCap NSZ 1", 2", 5", 8"

mdi AseptiCap NSZ positively charged Nylon 66 membrane capsule filters are absolute retention, serial filtration devices for sterilization of liquids. The upstream layer with larger pore size protects the downstream final layer for enhanced throughputs.

The positive charge of the membrane offers enhanced capability to retain negatively charged contaminants such as endotoxins and colloids even smaller than the membrane pore size rating.

These filters are biologically inert, autoclavable, heat resistant, exhibiting wide chemical compatibility, and are suitable for a large number of filtration and sterilization applications including ophthalmic, and injectable solutions.

  • Positively charged to retain contaminants smaller than pore size rating
  • High flow rates and throughputs
  • Minimal extractables
  • High heat resistance
  • Wide chemical compatibility
  • Biologically inert
  • Hydrophilic
  • Filtration of pharmaceutical solutions
  • Sterilizing filtration of wide variety of compatible organic solvents
  • Sterilization of laboratory disinfectants
  • Filtration of buffers and other non-aqueous solutions
