Our Mastelf 2mL ND9 Total Recovery Vials are specially designed for laboratories requiring maximum sample recovery, ultra-low residual volume, and high analytical precision. Featuring a 9-425 screw thread and standard 12 × 32 mm dimensions, these vials are fully compatible with most HPLC, UHPLC, GC, and LC-MS autosamplers.
Unlike standard autosampler vials, the Total Recovery Vial incorporates a permanently formed conical reservoir at the bottom of the vial, concentrating the sample into the lowest point. This design allows the autosampler needle to withdraw nearly the entire sample, minimizing dead volume and reducing valuable sample loss.
Available in clear and amber glass, Mastelf Total Recovery Vials are ideal for trace analysis, biological samples, pharmaceutical research, forensic testing, environmental analysis, and other applications where every microliter matters.

At Mastelf, we develop laboratory consumables that combine precision manufacturing, premium raw materials, and strict quality control to meet the requirements of modern analytical laboratories.
Our Total Recovery Vials are manufactured from high-quality Type 1 borosilicate glass, ensuring excellent chemical resistance, dimensional consistency, and low extractables. The precision conical reservoir is engineered to minimize residual sample volume and improve injection reproducibility, making these vials an excellent choice for laboratories working with precious or low-volume samples.
As a trusted supplier of chromatography consumables, Mastelf provides dependable alternatives to leading brands while maintaining consistent product quality and reliable analytical performance.
A Total Recovery Vial features a precision conical reservoir that concentrates the sample at the bottom of the vial, allowing nearly complete sample aspiration and minimizing residual volume.
A standard ND9 vial has a flat bottom, while a Total Recovery Vial incorporates a conical reservoir that significantly improves sample recovery and reduces sample loss.
Total Recovery Vials are recommended for low-volume, high-value, trace-level, or difficult-to-obtain samples, where maximum sample utilization is essential.
Yes. Mastelf 2mL ND9 Total Recovery Vials are compatible with major autosamplers from Agilent, Waters, Shimadzu, Thermo Scientific, PerkinElmer, CTC Analytics, and other leading manufacturers.
Yes. We offer both clear and amber Type 1 borosilicate glass versions to meet routine laboratory applications and the storage requirements of light-sensitive samples.
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.
