Biogeneral makes tubing from Chemours™ Teflon™ AF 2400.
(Visit the Teflon™ AF 2400 website here)
Specific Permeability:
Exceptional permeability and outstanding solvent and chemical resistance have made Teflon™ AF 2400 the preferred material for manufacturing highly efficient specific degassing devices.
Teflon™ AF 2400 Light Guide:
Excellent optical clarity and extremely low refractive index. Teflon™ AF 2400 tubing forms an optical fiber when filled with virtually any transparent liquid, including water.
Teflon™ AF 2400 Index of Refraction 1.29
H2O Index of Refraction 1.33
*Raman or Fluorescence Spectroscopy: Liquid Core Teflon™ AF 2400 light guide can enable up to 1000 fold intensity enhancement relative to conventional sampling methods.
*Absorbance Spectroscopy: Liquid Core Teflon™ AF 2400 capillary hollow fibers can provide path lengths two to three orders of magnitude longer than those of current sample cells, enhancing sensitivity and allowing small sample volume.
