Our glass ND9 vials are manufactured from high-quality hydrolytic class glass, ensuring excellent chemical resistance and sample stability.
Our ND9 plastic vials are made from non-disintegrating polypropylene, produced using a special spin-cast process to ensure maximum strength and dimensional accuracy.
Our high recovery vials feature a conical bottom design, helping to minimize sample loss and improve sample utilization.
We offer both glass integrated vials and PP integrated vials:
Compared with loose inserts, interlocked inserts are fixed inside the vial, preventing movement during transport and reducing contamination risk.
Our vials are supplied in specialized packaging designed to reduce breakage during transportation, ensuring product integrity upon delivery.
Our 2mL ND9 screw vials are compatible with autosamplers including:
Our ND9 screw vials are widely used in:
At Mastelf, we focus on providing high-quality alternatives to leading brands. Our vials are manufactured using clean production processes and premium raw materials, which helps reduce background interference and ensures reliable analytical results.
We work closely with laboratories and research institutions worldwide, delivering products that match the performance of major brands while offering a practical and stable solution.
Our ND9 screw vials feature a 9 mm wide opening, which allows easier needle access and is more suitable for high-throughput analysis. Compared with ND8, ND9 vials are generally preferred when better injection efficiency is required.
Yes, our ND9 PP vials are made from non-reactive polypropylene and are recommended for PFAS analysis when used with fluorine-free closures, helping reduce background interference.
Yes, our ND9 screw vials are designed as a high-quality alternative to major brands such as Agilent, Waters, and Thermo Scientific, offering reliable performance for routine and advanced analytical applications.
Our high recovery vials feature a conical bottom design, which helps reduce sample residue and improve sample utilization, especially for low-volume or precious samples.
Yes, we offer pre-assembled cap and septa sets, which are ready to use. This helps save time, improve workflow efficiency, and ensure consistent sealing performance.
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.
