Agilent Cap, Crmp, HS, 20mm, BiM, PTFE/butyl, 1000pk (Agilent part 5191-6638) is a 20 mm crimp-style headspace cap supplied in a 1,000‑piece pack. The caps include a bi‑layer PTFE/butyl septum and are intended to close 20 mm headspace/crimp vials for GC headspace sampling, storage, and autosampler use. They provide a secure crimp closure and a PTFE barrier to minimise sample‑septa interaction during headspace analyses.
Key Features:
- Cap type: Crimp headspace cap (for 20 mm crimp vials).
- Cap size / closure diameter: 20 mm (ND20).
- Septa construction: Bi‑layer PTFE/butyl septum (PTFE barrier over butyl).
- Pack quantity: 1,000 caps per pack (X1000 format).
- Intended technique: Headspace (designed for HS/GC autosampler workflows).
Advantages:
- Secure crimp closure reduces risk of sample tampering and loss—suitable for volatile analytes and headspace work.
- PTFE/butyl bi‑layer septum provides a chemically inert PTFE barrier to limit leaching and sample interaction.
- Sold in bulk 1,000‑piece packs to lower per‑cap cost and reduce frequency of reordering for high‑throughput labs.
- Designed for compatibility with standard 20 mm crimp vials and common autosampler platforms used in GC/HS applications.
