Description

Dependable separation performance and affordable. Use SureSTART™ 20 mL Glass Crimp Top Headspace Vials (Level 1) for everyday GC headspace analysis

Thermo Scientific™ SureSTART™ 20 mL Crimp Top Headspace Vials (Level 1) offer an affordable choice for everyday chromatography for all headspace GC instruments. Designed for labs that need reliability and value, these vials help provide consistent results for QA/QC workflows and routine analytical applications.

These vials are made to withstand higher temperatures and internal pressures required for volatile gas analyses.

Made with clear glass, SureSTART™ Level 1 glass vials meet US, EU, and JPN Pharmacopeia requirements and are Specification Certified to ensure autosampler-compatible dimensions.

Pair them with Thermo Scientific™ SureSTART™ 20 mm aluminium crimp caps and septa using a manual or electronic crimper tool to maintain sample integrity throughout daily operations.

Available as round or flat base:

• Round base vials are compatible with most autosamplers and more easily handled by robotic arms that lift the vial from the tray
• Flat base vials maximize heating efficiency in manual headspace sampling and are required for use in some instrument models

Key Features

• Made to withstand higher temperatures and internal pressures for volatile gas analyses
• For a secure, leak-free seal, pair with SureSTART™ 20 mm crimp caps and septa
• Use Thermo Scientific™ manual or electronic crimpers and decrimpers to seal and remove your crimp caps
• Write-on patch for straightforward sample labeling

Performance Level 1 – for Everyday Analyses

• Identified by a single wave on the vial
• Meets US, EU, and JPN Pharmacopeia requirements
• Compatible with GC headspace workflows
• Suitable for QA/QC applications using core detectors like UVD, RID, FLD, ELSD, FID, NPD, ECD, and CAD
• Not recommended for use with mass spectrometers

Specification Certified

Frequently Asked Questions (FAQs)

When should I use a headspace vial for my chromatography workflow?

Headspace vials are used when you want to analyze the gaseous phase of the sample rather than the liquid phase. These vials have a thicker glass wall to withstand higher temperature and internal pressure for the analysis of volatile gas in the vial’s headspace. Headspace vials with 20 mm crimp tops and 18 mm screw tops in sizes ranging from 6 mL to 20 mL are available in clear or amber glass. Choose from a round or flat base with a beveled or square edge finish.

Round base vials are compatible with most autosamplers and are more easily handled by robotic arms that lift the vial from the tray.

Flat base vials maximize heating efficiency in manual headspace sampling and are required for use in some instrument models.

The bevel edge on a vial lip provides additional sealing power for greater leak resistance under high pressure.
