DiamondPure Aluminum Crimp Seal Overview
The DiamondPure Aluminum Seal for 2mL Chromatography Vials from Globe Scientific delivers a secure crimp closure for analytical sample storage. Designed with an 11mm finish and a natural-color aluminum cap, this seal pairs with standard 2mL crimp-top vials used across chromatography workflows.
Each cap carries a bonded PTFE/red rubber septum. PTFE provides a chemically inert contact surface against your sample, while red rubber backing supports a reliable seal during storage and instrument sampling. Crimp closures help maintain consistent sealing torque, reducing operator-to-operator variability versus manual screw caps.
Packaged in bags of 100, these seals suit busy labs running high sample volumes. Bulk master-case ordering through LabSupplies.com keeps consumable supply steady for routine GC and HPLC operations.

Laboratory Applications
Crimp-top aluminum seals secure 2mL vials for gas chromatography and liquid chromatography sample preparation. Analysts rely on these closures to protect samples from evaporation and contamination between collection and instrument injection. The PTFE-faced septum suits contact with a wide range of organic solvents and aqueous samples typical in analytical labs.
Pharmaceutical QC, environmental testing, food and beverage analysis, and academic research facilities use 11mm crimp seals for autosampler-ready vial storage. Consistent crimping supports reproducible septum penetration during automated sampling. Sealed vials also help preserve sample integrity during short-term storage and transport between departments.
