Aluminum seals provide a sturdy cap to crimp-top vials, with wide orifices for easy needle insertion.

• Crimp-top vial compatibility
• Economical
• Silver aluminum

Aluminum seals are the preferred choice for use with manual crimping tools, and for autosamplers that do not employ magnetic pick-up transport.

Wide 13 mm openings decrease the number of broken needles, and aluminum fabrication imbues these seals with great durability.
