If you really want to know what happens inside your vial take a look at the Polyvial V-PETG from Zinsser Analytic.
These clear plastic vials are made from polyethylene-glycol-terephthalate which make them a non-breakable substitute for glass vials.
They are resistant to acids, alkalines and most solvents and are available in 4ml and 50ml volumes with self sealing caps which give a perfect gas-tight seal without a liner.
