As reported by Thermo Scientific, some budget minded laboratories may try to save money by washing their used autosampler vials and reusing them. However, these products are designed to be disposable and reuse can cause numerous QC issues, such as contaminant peakssample loss, and physical deformations on the glass surface. In these microscopy images, you can see the damage caused by washing.

As a result, the user may observe a number of detrimental effects. Evaporation may increase due to insufficient sealing between the cap and the vial threading. The vial is more brittle and more susceptible to breaking. Lastly, silanol groups may now be exposed to the surface, leading to adsorption of basic compounds.
