The Agilent UltraClean 18 mm magnetic screw cap (part no. 5188-2759) is a headspace vial closure supplied with a bi-layer PTFE/silicone septum in a 100‑per‑pack format. It is intended to seal 18 mm screw‑thread headspace vials for GC headspace sampling and autosampler use, offering an inert PTFE contact surface and compatibility with common autosamplers. The caps are steel magnetic screw closures rated to withstand elevated headspace temperatures.

Key Features:

  • Cap size: 18 mm (ND18 closure).
  • Pack quantity: 100 caps per pack.
  • Cap material: Steel magnetic screw cap.
  • Septa: Bi‑layer PTFE/silicone septa (top white, bottom blue).
  • Maximum temperature: 180 °C.
  • Intended technique: Headspace; compatible with CTC and Shimadzu autosamplers.

Advantages:

  • PTFE/silicone bi‑layer septum provides an inert sample contact surface to minimize adsorption and contamination.
  • Magnetic steel screw design secures caps for automated headspace sampling and is compatible with common autosamplers.
  • Rated to 180 °C, suitable for elevated headspace vial temperatures during equilibration.
  • 100‑pack format reduces frequency of reordering for routine analytical workflows.
