Provide positive seal
- Easy removal
- Large target area
Snap caps for use with autosampler vials are designed to provide a positive seal yet are easy to remove with resorting to crimping or decapping tools. These vials are suitable for high volume, quick turnaround sampling and provide a large target for needle penetration. Vials are not recommended for long-term sample retention. Snap caps are manufactured from polyethylene and are available in five different colors. Caps with starbursts allow easy needle penetration.
