Start from your autosampler: it decides the vial size and neck. Then pick the glass colour and the cap.
Step 1: Neck size and closure
| 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.
Step 2: Clear or amber glass
Use amber glass for light-sensitive compounds. Use clear glass for everything else, so you can see the fill level and any particles.
Step 3: Caps and septa
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.
Step 4: Small sample volumes
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.
Questions buyers ask
Do 9 mm caps fit 10-425 vials?
No. A 10-425 vial needs a cap with a 10-425 thread. Email sales@erohe-lab.com if you cannot find a matching cap in the caps range.
When do I need a 10-425 vial?
Only when your autosampler or method specifies it. Most current HPLC autosamplers use 9 mm short-thread vials.
Are these vials the same size as other 2 ml vials?
Yes, the body is 11.6 × 32 mm, so they fit standard 2 ml vial racks; only the neck and thread differ.
