Our Mastelf 2mL ND9 Screw Glass Vials with Integrated Insert are specially designed for low-volume and high-precision autosampler applications. Featuring a 9-425 screw thread and standard 12 × 32 mm dimensions, these vials are fully compatible with mainstream autosampler systems.
The integrated (fused) insert design means the insert is permanently bonded into the vial during manufacturing. This eliminates insert movement, significantly reducing the risk of sample loss, contamination, and positioning errors.
Available in both clear and amber glass, these vials are ideal for routine analysis as well as light-sensitive samples.

Our ND9 integrated insert vials are widely used in:
At Mastelf, we focus on delivering high-quality alternatives to leading brands.
Our vials are manufactured using:
This ensures:
It is a vial where the insert is permanently fused into the vial, forming a single structure.
They provide better recovery, stability, and reduced contamination compared to loose insert vials.
Typically low-volume samples (~300µL).
Yes, they follow standard 12 × 32 mm ND9 format.
Yes, both clear and amber options are available.
An autosampler vial is a small, specially designed container used in laboratory settings to hold liquid samples for automated injections into analytical instruments like chromatographs or mass spectrometers. Imagine it as a tiny, high-tech cup for your precious liquid samples!
Reusing vials and septa can mess up your chromatography and cause your assays to fail. You might have to redo the whole experiment, which can be time-consuming and frustrating.
Screw-top vials are the go-to for HPLC and LCMS. You don’t need any special tools to put the cap on or take it off. Crimp vials are the preferred choice for GC analysis. They’re the gold standard when it comes to preventing sample evaporation.
High recovery vials are indeed a specific type of container used in laboratory settings, particularly in chromatographic analyses like HPLC and LCMS. They’re designed to minimize sample loss on the vial walls, meaning you get more of your precious sample available for injection and analysis, leading to potentially better results.
Here’s what makes high recovery vials special:
When would you need to use high recovery vials?
Things to consider when using high recovery vials:
Overall, high recovery vials are a valuable tool for any chromatographer seeking to maximize sample recovery, improve analysis accuracy, and potentially reduce costs in the long run. If you’re working with limited samples, sticky analytes, or sensitive assays, consider using high recovery vials for optimal results.
