2ml ND8 Screw Vial

The 2mL ND8 Screw Vial is a standard autosampler vial designed for chromatography sample storage and routine laboratory analysis. Featuring an ND8 / 8-425 screw neck and a standard 32 mm vial height, it is widely used in HPLC, GC, and other analytical workflows that require secure sealing and reliable sample handling. Official product data from Agilent and Shimadzu shows this vial format as a standard 2 mL class / 1.5 mL usable-volume class vial in the 12 × 32 mm / 32 × 11.6 mm format.

Designed for use with matching 8 mm screw caps and septa, the ND8 screw vial is a practical option for laboratories that need stable sealing, easy handling, and broad autosampler compatibility. Agilent and Thermo Fisher both treat 8-425 screw-top vials as a standard vial family in their compatibility references.

Shimadzu and Other Common Brands

Shimadzu officially sells ND8 screw vials in 32 × 11.6 mm format, which supports the positioning of ND8 as a standard vial type in Shimadzu workflows. Other brands commonly associated with this vial format in compatibility references include CTC/LEAP, Gilson, Jasco, Knauer, Hitachi/VWR, Beckman, and Spark Holland.

Compatibility Note

Compatibility may vary depending on the autosampler tray, vial plate, rack holder, needle geometry, and instrument configuration. Thermo Fisher’s official chart notes that some autosamplers may require optional vial trays or configuration changes to use all listed vial types. For bulk orders, it is best to confirm the required vial dimensions and tray format with your instrument model.

Available Options

The 2mL ND8 Screw Vial is commonly available in:

• Clear glass
• Amber glass
• With or without write-on patch

Shimadzu’s official ND8 listings include clear and amber versions in the same general format, showing how this vial style is commonly offered in multiple configurations.

Applications

The 2mL ND8 Screw Vial is suitable for:

• HPLC analysis
• GC analysis
• Autosampler sample injection
• Routine laboratory testing
• Pharmaceutical analysis
• Environmental analysis
• Food and beverage testing
• Chemical analysis
• Research laboratories
  This application range is consistent with how Agilent, Thermo Fisher, and other chromatography suppliers position 8-425 screw-top autosampler vials.

Clear vs. Amber

Clear ND8 Screw Vials are suitable for routine applications where sample visibility is important.
Amber ND8 Screw Vials are recommended for light-sensitive samples that require protection from UV or visible light exposure during storage and analysis. Both Agilent and Shimadzu offer amber ND8 / 8-425 vial variants in this same standard format.

Why Choose ND8 Screw Vials?

ND8 screw vials are widely used because they combine a standard autosampler format with practical screw-cap operation and broad instrument compatibility. Official compatibility references from Agilent and Thermo Fisher show that 8-425 screw thread vials remain a mainstream format for many HPLC and GC sample handling systems.

Precautions

• Please use compatible ND8 / 8-425 screw caps and septa.
• Confirm vial compatibility with your autosampler tray and rack before routine use.
• Choose amber vials for light-sensitive samples.
• Store vials in a clean, dust-free environment before use.
• For critical methods, verify vial suitability during method validation.
  These precautions are consistent with official compatibility guidance indicating that tray and platform details can affect actual fit.
