Start from your autosampler: it decides the vial size and neck. Then pick the glass colour and the cap.
| Neck | Closure | Typical use |
|---|---|---|
| 9 mm short thread (9-425) | Screw cap with septum | The most common HPLC format; wide opening, easy to fill |
| 8 mm (8-425) | Screw cap with septum | Older and some specific autosamplers |
| 10 mm (10-425) | Screw cap with septum | Specific autosampler models |
| 11 mm crimp or snap | Aluminium crimp cap or snap cap | GC and volatile samples (crimp seals tightest) |
| 18 mm and 20 mm | Magnetic screw or crimp cap | Headspace GC |
Standard 2 ml vials measure 11.6 × 32 mm (often written 12 × 32 mm). Check the vial format in your autosampler manual; a free sample lets you test the fit in your rack.
Use amber glass for light-sensitive compounds. Use clear glass for everything else, so you can see the fill level and any particles.
PTFE/silicone septa suit most HPLC and GC work and reseal for repeat injections. Pre-slit septa reduce needle wear and stop a vacuum forming in the vial. Order caps and vials together: on EROHE, equal packs of 9 mm vials and caps get 5% off both.
For volumes under 1 ml, use a glass insert in a standard vial, or a vial with a built-in conical insert, so the needle can still reach the sample.
A 9 mm short-thread screw cap (ND9). The in-stock blue cap with a PTFE/silicone septum fits these vials, and equal packs of vials and caps get 5% off both.
PP vials suit samples that adsorb to glass, such as some proteins and peptides, and samples where glass ions are a concern. Glass is the better choice for most organic solvents.
A one-piece 0.3 ml vial with the insert bonded to the base, so small samples sit within needle reach without a separate insert.
USP type 1 refers to borosilicate glass with high chemical resistance. Product names state where the vial is listed as USP type 1.
