Pre-Assembled Kits Save Time and Ensure Consistency
Autosampler kits combine a vial, cap, and pre-inserted septum in a single ready-to-fill unit. This eliminates the manual assembly step, ensures consistent septa orientation, and reduces the risk of contamination from handling individual components. Kits are ideal for high-throughput labs processing large sample batches where speed and reproducibility matter.
KIT SELECTION GUIDE
Kit Configurations
| Configuration | Closure | Glass | Best For |
|---|---|---|---|
| Screw Cap Kit | 9-425 thread + PTFE/Silicone septum | Clear or Amber | Routine HPLC, LC-MS, GC liquid injection |
| Crimp Cap Kit | 11mm crimp + PTFE/Butyl septum | Clear or Amber | Headspace GC, volatile organic analysis |
| Snap Cap Kit | 11mm snap-on + PTFE/Silicone septum | Clear or Amber | High-throughput screening, fast capping |
💡Why Use Kits Instead of Separate Components?
Pre-assembled kits guarantee that every vial has the correct septum seated flush and facing the right direction. This matters for autosamplers with needle penetration depth settings — a misaligned septum can cause needle damage, leaks, or injection failures. Kits also reduce bench time by 30–50% compared to manual assembly.

Autosampler Kit FAQ
Our kits are factory pre-assembled. Each vial arrives with the cap and septum already in place. Simply open the package and fill — no assembly required.
9-425 screw cap kits fit the vast majority of HPLC and GC autosamplers from Agilent, Waters, Shimadzu, and Thermo. 11mm crimp kits are for headspace autosamplers. 11mm snap kits fit snap-cap compatible trays. Check your instrument manual for the required closure type.
Kit pricing is comparable to buying individual components. The labor savings from eliminating manual assembly typically make kits more cost-effective overall, especially in labs processing 50+ samples per day.
Yes. All kit configurations are available in both clear and amber glass. Amber kits block UV light below approximately 450 nm, protecting photosensitive compounds like vitamins, PAHs, and certain pharmaceuticals during autosampler queue time.
Yes. We offer kits with certified clean vials that include lot-specific certificates of analysis. These are recommended for trace analysis, EPA methods, and pharmaceutical QC applications where extractable contamination must be documented.
