Capillary, methyl deactivated fused silica

Product information "Capillary, methyl deactivated fused silica"

Coated fused silica tubing for GC capillary applications.

  • High homogeneity
  • Chemically inert
  • Standard polyimide temperature resistance up to 380 °C
  • Polyimide coating is chemically resistant
  • Low dielectric constant, low dielectric loss
  • Impermeable to all gases (except H2, He)
  • Free of thermal hysteresis
  • High intrinsic tensile strength
  • Very low thermal expansion


Use with hydrofluoric acid, phosphoric acid, alkalis and alkali metal-containing compounds should be avoided, as this can lead to dissolution of the quartz glass and devitrification of the surface.
