Phthalate-free ND11 crimp cap closure
MS detectors with decreasing detection limits for interfering peaks increase the demands on the sealing of closures for crimp rim bottles (vials). Special analytical applications also require optimum sample integrity. The solution is the phthalate-free 11mm crimp cap closures with aluminum septum and the following properties:
- Elastomer- and halogen-free septum made of aluminum foil (interference peaks due to plasticizers can be completely excluded!)
- A groove in the aluminum flanged cap ensures a firm hold and prevents the aluminum sealing washer from falling out during transport
- Maximum tightness thanks to a plasticizer-free fluoroplastic O-ring placed above the aluminium sealing washer Elastomer and halogen-free septum
Areas of application
- Phthalate – analytics
- Elastomer and plastomer analysis
- Analysis of fluorinated/halogenated organic compounds
- VOC (volatile organic compounds)
- Analysis of polymerization catalysts
- Silicone and silicate analysis
- Suitable for storing standards or reactive substances that can attack organic septum materials.
