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
- 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.
- 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.
- 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.
- Blue Silicone/Clear PTFE liner:
- AntiSpin Design:
- Prevents the cap from spinning during crimping or autosampler operation, ensuring a secure seal.
- Pre-Slit Septa:
- Not pre-slit, allowing users to retain sample integrity until piercing.
- Universal Compatibility:
- Standard 20 mm crimp closure size fits most headspace GC vials, including CTC, PerkinElmer, and Agilent systems.
