Three closure types: crimp, screw or snap ring
Brown supplies autosampler vials in three closure types, each with its own advantages:
Crimp-top vials (11 mm) offer the best pressure resistance and are closed with an aluminium crimp seal. The standard choice for GC analyses in which the needle pierces the septum. Available with a wide opening for less risk of needle damage.
Screw-top vials (8-425 or 9-425) are closed with a polypropylene screw cap. Quick and easy to open, no crimper needed. Ideal for HPLC and routine LC applications.
Snap ring vials (11 mm) combine the convenience of a snap-on cap with the rigidity of a vial with a fixed neck ring. Suitable for both 11 mm crimp seals and snap caps.
XL® Wide Opening vials (screw cap 9-425)
Brown XL® vials have a 40% wider opening than standard autosampler vials. This considerably reduces the risk of bent or damaged needles, especially in automated systems with high throughput. Specially designed for the Agilent 7673, 7673A and comparable robot arm autosamplers.
Available in clear and amber, with and without writing spot. The matching XL® 9-425 screw caps are available in 6 colours (natural, black, blue, red, green, yellow) and with a wide choice of pre-assembled septa.

Screw caps and septa
Brown supplies a complete range of polypropylene screw caps for autosampler vials, available in 5 colours. All caps are available with a pre-assembled septum in the following materials:
| Septum | Property | Application |
|---|
| Rubber/ETFE | Economical | Routineanalyse |
| Silicone/PTFE | Excellent resealability | Multiple injections |
| PTFE/Silicone/PTFE | Reduces coring | Trace-analyse |
| Butyl/PTFE | Lage permeabiliteit | Long-term storage |
| Ultra Clean Silicone/PTFE | Ultra-low bleed, conditioned | GC/MS |
| Silicone/PTFE single/cross/star slit | Pre-slit | Easy needle penetration |
Screw caps are available in sizes 8-425 (for standard and screw-top vials) and 9-425 (for XL® vials). Open top caps with separate septa are also available for maximum flexibility.
Clear or amber: when do you choose which version?
Choose amber autosampler vials when your samples are sensitive to UV light, such as certain vitamins, hormones, pesticides or dye-containing compounds. For most routine GC and HPLC applications, clear vials are sufficient.
Vials with a writing spot make manual labelling easier and prevent sample mix-ups, reducing the risk of errors in high-volume routine analysis.
