PEEKsil is constructed from a core of smooth precision bore fused silica tubing bonded to a PEEK outer sheath. It is manufactured to exacting tolerances of bore size and concentricity, for reproducible flow rates and reliable connections. The separation achieved is easily lost in tubing and connectors as a result of dispersion. PEEKsil reduces dispersion and therefore loss of efficiency, sensitivity and resolution. Features and benefits. Maximum temperature: 100ºC Inert smooth flow path, to minimize band broadening Precise inside bore diameter Flexible and robust Lower sample carryover Color coded for easy identification of internal diameter Perfectly square cut and polished ends Capable of withstanding high pressures Effective pH range of 0-10 (not compatible with hydrofluoric acid) Compatible with most organic solvents (unlike PEEK). To optimize your PEEKsil connections utilize our PEEKLok fittings, available in 1/16" to suit 10-32 UNMeer tonenMinder tonen
