Introduction to Glass sample vials

Glass sample vials are specialized containers used for storing, handling, and analyzing chemical testing samples on analytical instrument systems such as gas chromatography (GC, GCMS). Featuring chemical inertness from glass materials, these vials help preserve sample integrity throughout automated injection or storage processes.

When choosing glass sample vials, users should consider capacities such as 2ml, 10ml, or 20ml to suit the autosampler tray. Regarding color, light-sensitive samples require amber glass, while standard samples use clear glass. Neck designs include standard 8-425 screw threads or crimp tops, paired with PTFE/Silicone septa to prevent evaporation. Depending on practical needs, buyers can choose flat-bottom designs, graduated marks, write-on patches, or wide-mouth openings for convenient sample handling.

When should amber glass vials be used instead of clear glass?

Amber glass vials are used for light-sensitive compounds to minimize photochemical degradation of the sample. Clear glass is suitable for standard samples and allows direct visual inspection of the solution inside.

What capacities and cap types are available for sample vials?

The products are available in common capacities including 2ml, 10ml, and 20ml with flat bottom designs. Cap types include snap caps or screw caps (such as 8-425 thread standard) equipped with PTFE/Silicone septa to ensure tightness for GC and GCMS analytical applications.

What are the benefits of the graduated markings and labeling area on vials?

Graduated markings allow users to easily estimate the volume of liquid loaded into the vial. The labeling patch enables writing sample identification codes, reducing the risk of mix-ups between analytical batches.

What is the standard packaging specification for glass vials?

Glass sample vial products are currently packed in a standard specification of 100 pcs/pack. Please contact Hoa Viet for detailed advice on vials and septa caps compatible with your laboratory instruments.
