High-pressure HPLC systems operating above 600 bar impose dynamic shock loads on sample vials and closures that can trigger glass rupture, cap loosening, and septum blowout. This article examines the material science behind these failure modes — including Griffith flaw propagation, PP thread relaxation, and septum friction mechanics — and provides practical countermeasures from consumables selection to instrument parameter optimization.
