Autosampler Headspace Vials: Integrity Under Pressure
Headspace gas chromatography (GC) requires a vial that can maintain a perfect seal at elevated temperatures. Our premium Autosampler Headspace Vials are engineered to provide maximum safety, chemical inertness, and compatibility with the industry’s leading automated systems.
Whether you are analyzing volatile organic compounds (VOCs) in water or residual solvents in pharmaceuticals, our vials ensure your results are reproducible every time.
Precision Engineering for Every Application
Our vials are manufactured from USP Type I Borosilicate glass, ensuring minimal ion leaching and superior thermal shock resistance.
1. Flat Bottom vs. Rounded Bottom Vials
Flat Bottom Vials: Ideal for manual headspace sampling or instruments with flat heating blocks. They offer more surface area contact for even heating.
Rounded Bottom Vials: The preferred choice for automated “shaking” or “rotating” autosamplers. The rounded base is more structurally sound, allowing the vial to withstand higher internal pressures and move easily in robotic arms.
2. Crimp Top vs. Screw Top Vials
Crimp Top (20mm): The industry standard for high-pressure applications. These provide the most secure seal, minimizing the risk of volatile loss during the heating cycle.
Screw Top (18mm): Designed for convenience and ease of use. These do not require a crimping tool and are ideal for high-throughput labs where speed and consistency are paramount.

The Importance of the Septum
A vial is only as good as its seal. We provide high-performance closures to match your headspace requirements:
PTFE/Silicone Septa: Excellent chemical resistance and resealing capabilities.
Pressure Release Caps: Safety-engineered to allow controlled venting if the internal pressure exceeds safe limits (approx. $3.0 \pm 0.5$ bar).
Why Trust Our Headspace Vials?
Universal Compatibility: Fully compatible with Agilent, Gerstel, PerkinElmer, Shimadzu, and CTC PAL autosamplers.
Certified Cleanliness: Every batch is processed in a clean-room environment to ensure zero trace-level contamination.
Dimensional Accuracy: Precise neck geometry ensures your autosampler needles never miss the target, reducing downtime and mechanical wear.
