Procurement Decision – Which Vial Type?
| Application Need | Recommended Vial Type | Key Feature | Risk if Wrong |
|---|---|---|---|
| Volatile samples / GC-MS / long storage | Crimp top | Permanent aluminum seal | Sample evaporation, low sensitivity |
| Routine HPLC, reusable workflows | Screw top (9-425) | Reusable vial, easy capping | Higher evaporation risk |
| High-throughput, manual operation | Snap top | Tool‑free, audible click | Seal integrity lower for volatiles |
| Headspace GC (VOC analysis) | Headspace vials, 10/20 mL | Thicker wall, pressure resistant | Vial cracking, analyte loss |
| Long‑term sample storage | Storage vials, 20/40 mL | USP Type I glass, PTFE liner | Sample degradation, pH shift |
| Low volume samples (<200 µL) | Vial inserts | Conical/pulled‑point, spring options | Incomplete injection, wasted sample |

Frequently Asked Questions – Sample Vials
What is the difference between crimp, screw and snap top vials?
Crimp vials provide the best seal for volatile samples but require a crimping tool. Screw vials are reusable and convenient for routine HPLC. Snap vials offer tool‑free sealing with an audible click but lower evaporation resistance.
Which vial is best for headspace GC?
Use 20 mL headspace vials (crimp top) with PTFE/silicone septa. They have thicker walls to withstand internal pressure.
What insert should I use for very small sample volumes?
For 2 mL vials, use a 150 µL conical or pulled‑point insert. For viscous samples, add a spring (polyspring) to push the insert upward.
Can I get samples before placing a bulk order?
Absolutely. Request evaluation samples of any vial type – we ship free samples for qualified labs.
