Low-volume inserts for 9 mm threaded vials are small glass or plastic inserts placed inside standard 2 mL autosampler vials. They reduce the effective sample volume and improve sample recovery when only a small amount of liquid is available.
Handling low sample volumes
Ideal when you only have 5–300 µL of sample instead of a full 2 mL.
Prevents the autosampler needle from missing the sample.
Chromatography (HPLC/UPLC/GC) sample prep
Ensures reliable injection when working with precious or limited analytes.
Reduces sample loss due to adsorption on vial walls.
