Key Definitions ▸
Headspace Vial
A specialized vial used in gas chromatography to contain samples where the vapor phase (headspace) is analyzed, particularly useful for volatile compounds.
Crimp Cap
An aluminum cap applied with a crimping tool to create an airtight seal. Ideal for high-volatility samples and regulatory environments.
Screw Thread Vial
A vial sealed with a screw cap, offering fast, tool-free closure. Often used with automated platforms such as CTC/CombiPal autosamplers.
Magnetic Cap
A crimp or screw cap with an integrated magnetic liner to enable precise robotic handling in automated GC headspace systems.
Flat vs. Round Bottom
Headspace vials may use flat bottoms for stable autosampler seating or round bottoms for optimized heat distribution in equilibrated samples.
Frequently Asked Questions ▸
What is the difference between crimp and screw thread headspace vials?
Crimp vials provide the most secure seal for volatile samples, while screw thread vials are ideal for quick, tool-free closure and compatible with CombiPal systems.
Are your headspace vials compatible with all autosamplers?
Yes, Chrom Tech headspace vials are designed to meet industry-standard dimensions and are compatible with Agilent, CTC, PerkinElmer, and other leading GC systems.
Do you offer magnetic caps for robotic autosamplers?
Yes, we offer magnetic-lined crimp and screw caps specifically designed for robotic and CombiPal autosamplers to ensure precise handling and sealing.
