Additional Info:
The CTC-0952-AQ Ultra‑Pure Screw Caps are engineered for highest‑purity chromatographic applications where background interference must be minimized. These caps feature non‑pigmented silicone rubber and PTFE septa, with no added dyes or colorants, delivering exceptional chemical inertness.
Designed for 9‑425 thread, 12 × 32 mm autosampler vials, the septa are fitted into light blue, knurled polypropylene caps and manufactured using ultra‑clean materials to support LC‑MS, GC‑MS, and LC‑MS/MS workflows requiring maximum signal integrity.
These caps are an excellent choice for users seeking performance comparable to LC‑MS‑certified systems, including those used in Waters® Alliance and Acquity™ platforms, when a non‑pre‑slit septum is required.
