Overview
A plain neck vial is a cylindrical container featuring an unthreaded, smooth upper rim designed for crimping or heat-sealing. Typically manufactured from Type I borosilicate glass or high-density polyethylene (HDPE), these vessels undergo annealing to ensure chemical inertness and thermal shock resistance.
Application
- Pharmaceuticals: Compatible with lyophilizers and automated filling lines for sterile powders.
- Laboratory Analysis: Used in HPLC autosamplers and GC headspace systems.
- Chemical Storage: Paired with aluminum crimp caps for volatile solvent containment.
Precautions
- Operate within -20°C to 150°C; avoid rapid temperature gradients.
- Maintain internal pressure below 2 bar gauge during sealing processes.
- Inspect rims for micro-cracks prior to crimping to prevent seal failure.
