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
Which caps fit 8-425 vials?
8 mm screw caps (ND8) with an 8-425 thread. 9 mm short-thread caps do not fit this neck.
How does an 8-425 vial differ from a 9 mm short-thread vial?
Both are 11.6 × 32 mm, but the 8-425 neck has a narrower opening and a different thread. Use the format your autosampler manual specifies.
Which inserts fit 8-425 vials?
Inserts of 31 × 5 mm or 29 × 5 mm, sold in the 8 mm insert range in 150 µl and 250 µl.
What is the write-on spot for?
It is a white printed area where you can write a sample number with a lab marker.
