2.0 mL, 11 mm Poly Crimp Seal Caps: Snap-on or Crimp
The patented Poly Crimp Seal is versatile, working as either a snap-on or crimp-top cap.
Simply use a standard crimping tool to secure the Poly Crimp Seal onto any crimp-top
vial. It’s that easy!
• Works on any crimp style vial.
• Crimps smoothly and easily—no more sharp edges from an
aluminum crimp cap.
• Easily decaps using standard decapping tools.
• Eliminates inconsistent sealing that results from improper
crimping.
• Unique design holds the septum firmly in place.
• Provides better seal than snap caps.*
• Meets CONEG standards. The Poly Crimp Seal is free of
heavy metals and is easily disposed of or incinerated.
2.0 mL, 11 mm GC Snap Ring Cap with Septum
• Snaps on any crimp-style vial.
• Clear polypropylene cap provides a tighter seal than standard Snap Ring Cap.
• Good for pressurized injection systems.
• Save money! Use this snap cap when you don’t need to crimp.
*Based on continual use for 3–4 days.
