Polycarbonate Track-Etched membranes are manufactured under Class 100,000 conditions to be exceptionally contaminant free. Exhibit negligible adsorption/absorption of filtrate, precise pore size, narrow pore distribution, low tare weights, low trace element level.

  • Smooth, flat surface for even distribution in a single plane
  • Created with pore density and size precisely controlled
  • Biologically inert
  • Optically translucent (actually transparent in most pore sizes)
  • Not stained by most solutions
  • Nonhygroscopic
  • Superior strength, chemical resistance, thermal stability
  • Autoclavable

  • Thickness: 6 to 10μm
  • Tare weight: 1.0mg/cm2
  • Tensile strength: >3000psi
  • Residual ash: 0.92mg/cm2
  • Specific gravity: 0.94 to 0.97
  • Minimum burst strength: 10psi
  • Max. use temperature: 140°C (284°F)
