2） Product Overview

3） Key Features

• Diverse micro-volume inserts support micro-sampling requirements. They quickly convert standard full-volume vials into small-volume sampling vessels for convenient use.
• All inserts fit vials with a standard 5 mm inner opening diameter.
• Three styles optional: flat base, conical base, and conical base with polyspring.
• Conical bottom design enables complete extraction of trace residual samples.
• Flat-bottom inserts are easy to place and retrieve. They stand stably on workbenches without extra holders, ideal for frequent sample replacement and transfer.
• Cost-effective consumable for routine HPLC testing.
• Polyspring inserts automatically center samples and buffer collision between autosampler needles and glass inserts.
• Perfect dimensional matching for corresponding vial specifications.

4） Applications

Gas Chromatography (GC)：Micro-inserts cooperate with autosampler vials and injection ports to accurately transfer liquid or gaseous samples into GC instruments, securing excellent testing accuracy and repeatability.

Liquid Chromatography (LC / HPLC)：Micro-inserts extract liquid samples and deliver them to chromatography columns. The inserts precisely control injection volume and effectively prevent cross-contamination between different samples.
