8 mm Polyethylene Conical Starburst Snap Plugs
Manufacturer: JG Finneran Associates
The 8 mm Polyethylene Conical Starburst Snap Plugs from JG Finneran are high-performance closures designed for 8 x 40 mm shell vials. This specific conical design provides a tapered fit into the vial, ensuring a more robust and secure seal compared to standard flat-bottom plugs. Like the standard version, it features the "starburst" center—a thin, pre-scored section that facilitates easy needle penetration while maintaining sample integrity.
Description
Features:
- Enhanced Seal Integrity: The conical (tapered) shape creates multiple points of contact within the vial neck, providing a superior airtight seal that is highly effective at reducing the evaporation of volatile solvents
- Low-Force Needle Entry: The starburst center is designed to "give" easily when the autosampler needle descends, preventing needle blunting and ensuring the needle does not carry plastic debris (coring) into the sample
- Friction-Lock Security: The tapered design ensures that once the plug is seated, it is much less likely to become dislodged during the mechanical indexing of the autosampler carousel
- Inert Material: Made from LDPE, these plugs are chemically resistant to most HPLC and GC solvents, ensuring no plasticizers leach into your sensitive samples
Technical Tips:
- Application Strength: Because of the tapered conical design, these plugs may require slightly more downward pressure to seat fully compared to non-conical versions. Ensure the plug is completely flush with the vial rim for optimal autosampler performance
- Vial Compatibility: While designed for 8 x 40 mm vials, they are also compatible with most other shell vials that accept an 8 mm closure
