• Non-particulate generating construction

• Allows for clean samples; eliminates contamination
  due to sample holder material; reduces variables
  for accurate results

• Extruded plastic cards are rigid and non-porous

• Plastic cards do not absorb oils, fumes, or
  moisture to contaminate samples

• Membranes are “pre-stretched” for consistent
  tension across the aperture

 • Creates a thin, uniform viewing surface without
  ripples or aberrations for accurate, reproducible results

• Dual purpose membrane can also serve as a filter

• Allows sample to filter through the membrane,
  yet retain important properties for analysis
