Autosampler Vial

EPA VOC TOC Vials

EPA VOC TOC Vials are 20ml, 40ml, and 60ml borosilicate glass vials designed for volatile organic compound and total organic carbon analysis in environmental and industrial testing. They are available in clear and amber variants, assembled with polypropylene caps and 3.0mm PTFE/silicone septa, and are compatible with major autosampler brands including Shimadzu, C&G Container, EP Scientific/Thermo, SUEZ Sievers, and others. The vials are pre-cleaned and certified for use in purge-and-trap GC/MS applications.

Where It Is Used

Applications And Buyers

Application Scenarios

Storing and analysing water samples for volatile organic compounds using purge-and-trap GC/MS
Preparing soil and air matrix samples for VOC and TOC quantification in environmental monitoring
Holding calibration standards and blanks in trace-level organic analysis where extractables must be minimal
Conducting long-term sample storage with minimal headspace contamination due to robust sealing
Using in high-throughput laboratories that require consistent vial geometry and cap compatibility across multiple instrument platforms

Who It Is For

Environmental testing laboratories conducting EPA Method 524 and 8260 compliance testing
Industrial labs performing VOC and TOC analysis on process water, effluents, and air emissions
Contract testing labs serving regulatory clients requiring certified pre-cleaned vials
Laboratories using Shimadzu, C&G Container, EP Scientific/Thermo, SUEZ Sievers, and other major autosampler systems
Lab distributors sourcing certified vials with consistent geometry and compatibility across brands

Problems It Solves

Contamination from extractables in non-certified vials causing false positives in trace-level VOC analysis
Inconsistent cap fit or septa integrity leading to sample loss or evaporation during long-term storage
Lack of compatibility with major autosampler brands due to mismatched thread or vial geometry
Inadequate protection of light-sensitive analytes in clear vials during sample handling and storage
Need for in-house cleaning and certification of vials, increasing workload and risk of contamination

Comparison

Compared With The Alternatives

Versus Standard glass vials without certification

These vials are pre-cleaned and certified for purge-and-trap GC/MS, reducing background interference and eliminating the need for in-house cleaning

Versus Vials with silicone-only septa

PTFE/silicone septa offer better chemical resistance and lower extractables, especially for aggressive solvents and high-temperature analysis

Versus Vials with thinner septa

3.0mm thick septa provide better seal integrity and resistance to needle penetration, reducing sample loss during autosampling

Versus Vials with non-standard threads

24-400 thread ensures compatibility with major autosampler brands, avoiding fit issues and misalignment

Use Guide

How To Use It

Select clear vials for non-light-sensitive samples and amber vials for compounds sensitive to UV degradation
Use the 40ml vial for typical sample volumes in purge-and-trap analysis; 20ml and 60ml for smaller or larger volumes
Ensure the cap is tightened securely to prevent evaporation or contamination during storage
Do not reuse vials or septa; single-use design prevents carry-over and cross-contamination
Store vials in a clean, dry environment away from direct sunlight to preserve sample integrity
Verify compatibility with your autosampler before full-scale deployment

FAQ

Questions Buyers Ask

Are these vials certified for purge-and-trap GC/MS analysis?

Yes, the EPA VOC TOC Vials are pre-cleaned and certified for purge-and-trap GC/MS applications.

What is the thread standard for these vials?

The vials use a 24-400 thread, which is compatible with major autosampler brands including Shimadzu, C&G Container, EP Scientific/Thermo, and SUEZ Sievers.

What materials are used in the cap and septa?

The cap is made of polypropylene, and the septa are 3.0mm thick PTFE/silicone.

Can I use these vials with my Shimadzu autosampler?

Yes, the 24-400 thread and Class 300 geometry ensure compatibility with Shimadzu and other major autosampler systems.

What is the difference between clear and amber vials?

Clear vials are used for non-light-sensitive samples; amber vials protect light-sensitive analytes from UV degradation.
