Postnova fused silica capillary tubing

Fused silica capillary tubing

Postnova provides a great variety of flexible fused silica capillary products with inner diameters from 2 - 700 um and with numerous coatings available. They supply a wide range of tubing from thin walled polyimide coated flexible fused silica to thick walled silica quartz tubes without coating. They provide custom sizes, custom tolerances, and a wide range of durable and protective coatings with lowest tolerances to meet our customer’s needs.

Features:

• Internal diameters from 2 um up to approx. 700 um
• Outer diameters down from 90 um up to approx. 900 um
• Excellent chemical durability and inertness
• Silica and quartz that are stronger than steel
• Tight but still economical affordable tolerances
• Materials that are easy to cleave or cut
• Proven combination of silica and polyimide
• FS capillaries with unique strength/flexibility
• Low fluorescence background for stable reproducible use in on-column detection methods because of superior UV/Vis transmission when protective coating is removed
• High purity silica allows for precision laser machining of integrated value added features
• Avoid coating contact on the outside with organic solvents, acids or alkaline solutions, this might break/dissolve the coating
