Tubing (PEEKsil®)

PEEKsil is polymer-sheathed fused silica tubing, available in outside diameters of 1/32 inch or 1/16 inch, and in 0.36 mm. The sheathing polymer is polyether ether ketone (PEEK) that is mechanically strong and has ideal characteristics for sealing with conventional metal or polymer ferrule systems. PEEKsil may be used as a direct replacement for conventional stainless steel as well as a replacement for PEEK tubing used in liquid chromatography systems. The 0.36 mm OD material can be used directly in place of 0.36 mm OD fused silica tubing.
The PEEK polymer exterior coating and the fused silica combination makes PEEKsil very robust. PEEKsil is therefore capable of withstanding high pressures, making it ideal for capillary LC and LC-MS applications.
The fused silica internal wall provides an exceptionally smooth surface, free of imperfections, which ensures excellent flow characteristics. Solvent Compatibility
It is compatible with most organic solvents and is resistant to strong acids
pH range of 0-10. PEEKsil is not compatible with hydrofluoric acid.
PEEKsil is inherently straight, but is very flexible, which makes connection between columns, detectors and injectors easier than with more rigid stainless steel tubing.
