Capillary, phenyl 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.
