Confirm performance for the reagent-sensitive wavelengths and actual shielding requirements. Black appearance alone does not replace light-shielding validation of the complete fluid path.
Black PTFE Ferrule Tubing Assembly
FOREACH black PTFE ferrule tubing assemblies connect black PTFE tubing with matched threaded fittings and ferrules for reagent lines requiring light shielding in in-vitro diagnostic (IVD) and automated analytical instruments. No tube pre-flanging is required. Reference tubing IDs span 0.8–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm in specified pairs. Length, both end connections and line identification can be specified.
Standard connections fit M6×1 or 1/4-28 UNF flat-bottom ports, with fitting material, structure and ferrule selected for tube dimensions and port model. Evaluate shielding against reagent-sensitive wavelengths, tube-end connections and the actual installation. Protective sleeves and stop tubes are optional; text, numbers or logo labels can identify fluid paths. Samples to drawing, instrument integration and batch assembly are supported. Confirm working pressure and temperature for the specific dimensions, ports and complete assembly.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications.
