Flat Base Insert

Glass Inserts | for 2 mL Vials

These clear glass inserts are for 9mm LC and GC autosampler vials.

When analyzing samples with low volume, use an insert to maximize the injection volume. These glass inserts have a small total volume capacity of <400 μL, with a minimum residual volume of 2 µL. When placed and sealed inside a 2 mL vial, microsamples can be used in conventional autosampler trays.


  • Use 9 mm screw top vials, 11 mm snap top vials, or 11 mm crimp top vials with these inserts
  • Suitable for GC, HPLC/UHPLC, and mass spectrometry (MS) applications
