Autosampler Vials & Caps for HPLC & GC | Thermo Fisher

The glass vials are more compatible with the strong organic solvents used to solubilize liquid samples. HPLC: When processing samples in batches of less than 50 use vials as there is little advantage using a 96-well plate as the plate capacity would not be fully utilized.

How Glass Vial Quality Affects Data Accuracy - Labmate Online

Jun 22, 2020 · Poor glass quality can affect analytical applications in two broad ways: (i) analytes in the sample react with inorganic particles on the glass surface and are retained in the vial, resulting in skewed quantitation numbers, (ii) contaminant particles enter the sample stream and accumulate on the column, resulting in distorted peaks and directly

The importance of chemical composition for vial performance

The higher the metal content, the higher the COE. Some manufacturers offer budget vials with a COE in the range 70–71. This is because higher metal concentrations mean that significantly lower amounts of heat are required in the annealing process. It can reduce the cost of manufacturing by up to 75% but will affect vial performance.
