Crimp Top Vials

2 mL Crimp Top GC Vials

Chrom Tech’s 2 mL crimp top GC vials are the preferred choice for gas chromatography workflows requiring the most secure, evaporation-resistant seal. The metal crimp closure minimizes loss of volatile analytes, making these vials ideal for trace-level analyses, forensic applications, and any workflow where chain-of-custody or tamper-evident sealing is essential.

For consistent, ergonomic sealing, we recommend pairing these vials with a Chrom Tech electronic vial crimper, ensuring optimal seal integrity and reproducible GC results.

Key Definitions ▸
Crimp Top Vial
A GC vial designed to be sealed with a metal crimp cap, providing the tightest, most secure closure for volatile samples.
Crimp Cap Seal
A deformation-based seal formed by compressing an aluminum cap around the vial finish, creating an airtight, tamper-evident closure.
Volatile Sample Integrity
The ability of a vial and closure system to prevent analyte loss from evaporation, critical for GC methods involving high-volatility compounds.
Chain-of-Custody Compatibility
A requirement in forensic, clinical, and regulatory environments where vial closures must clearly show tampering or unauthorized access.
Electronic Vial Crimper
A handheld power-assisted tool used to apply consistent crimping force, improving ergonomics and ensuring reproducible sealing performance.
Frequently Asked Questions ▸
Why choose crimp top vials for GC applications?
Crimp top vials provide the tightest, most secure seal, making them ideal for high-volatility solvents and low-level GC analyses where sample loss must be minimized. The metal crimp closure also supports forensic and regulated workflows that require a tamper-evident seal.
Do crimp caps reduce evaporation more than screw caps?
Yes. The deformation-based crimp seal provides a superior vapor-tight barrier compared to threaded closures. This helps protect volatile analytes and improves long-term sample stability in GC workflows.
What tools do I need to properly crimp my GC vials?
Crimp caps must be applied with a manual or electronic crimper. Chrom Tech recommends an electronic vial crimper for ergonomic handling and consistent, repeatable seal integrity.
Are Chrom Tech crimp vials compatible with major autosamplers?
Yes. Our 2 mL crimp top GC vials are fully compatible with most standard GC autosamplers from Agilent, Thermo, Shimadzu, Scion, PerkinElmer, and more.
Why buy vials, caps, and inserts from Chrom Tech?
Chrom Tech offers excellent pricing on high-quality GC vials, caps, and inserts—along with fast, reliable shipping on the most popular configurations. Many of our vial formats and crimp caps are in stock and ready to ship, minimizing lab downtime.
