These high-quality clear glass inserts  are the optimal solution for chromatography analysis (HPLC/GC) when handling micro-volume samples.

📌 KEY APPLICATIONS:

• Optimized for Micro-Volumes: Designed to be placed inside standard vials when the sample volume is too low to be reliably extracted from the vial's bottom.

• Autosampler Support: Effectively raises the liquid level, allowing the autosampler needle to easily and consistently draw the sample.

• User-Friendly Design: The flat bottom allows the insert to stand upright independently on a benchtop, making sample preparation exceptionally easy (note: residual volume is slightly higher compared to conical inserts).

⚙️ TECHNICAL SPECIFICATIONS:

• Material: Premium, chemically inert clear glass.

• Volume/Capacity: 250uL.

• Dimensions: 31x5mm.

• Compatibility (Crucial): Fits perfectly and is designed EXCLUSIVELY for standard 2mL screw vials with an 8-425 (8mm) neck finish. Strictly DO NOT use with 9mm, 10mm, or 11mm vials.
