20mm Blue Bimetal Magnetic crimp cap with Blue Silicone/Clear PTFE septa Ultra Low Bleed (ULB) (0.125" Thickness)

The 20mm Blue Bimetal Magnetic Crimp Cap with Blue Silicone/Clear PTFE Septa is a high-quality crimp cap designed for headspace gas chromatography (GC) applications. Featuring Ultra Low Bleed (ULB) septa technology and a magnetic bimetal design, this cap ensures optimal sealing, minimal bleed, and compatibility with magnetic autosampler systems. The blue silicone/clear PTFE liner is chemically inert, making it ideal for sensitive analytical workflows.

Key Features

1. Ultra Low Bleed (ULB) Septa:
   • Minimal bleed ensures cleaner chromatographic baselines and improved sensitivity in headspace GC analysis.
   • Septa thickness of 0.125 inches provides robust sealing without compromising performance.
2. Magnetic Bimetal Cap:
   • The cap's bimetal magnetic design ensures compatibility with autosamplers requiring magnetic crimp caps.
   • Durable and resistant to deformation for reliable use in high-throughput systems.
3. Liner Material:
   • Blue Silicone/Clear PTFE liner:
     • PTFE (Polytetrafluoroethylene): Chemically inert and resistant to a wide range of solvents and compounds.
     • Silicone: Provides elasticity for a tight seal while maintaining resealability.
4. AntiSpin Design:
   • Prevents the cap from spinning during crimping or autosampler operation, ensuring a secure seal.
5. Pre-Slit Septa:
   • Not pre-slit, allowing users to retain sample integrity until piercing.
6. Universal Compatibility:
   • Standard 20 mm crimp closure size fits most headspace GC vials, including CTC, PerkinElmer, and Agilent systems.
