When to Use High Recovery Vials in Chromatography
High recovery vials play a vital role in analytical workflows where maximum sample recovery is essential. Laboratories commonly use these vials for two main reasons. The first is when working with limited-volume samples—recovering the final few microliters can be critical to obtaining accurate, reproducible results. The second is for workflows that require reinjecting the same sample multiple times, even if the sample isn’t limited. Using a total recovery vial helps ensure there’s enough remaining volume for subsequent injections without compromising sample integrity.
When High Recovery Vials Are the Best Choice
High recovery vials are most useful when your workflow is limited by sample volume or requires repeated injections.
- Limited-volume samples: When the final microliters matter, high recovery geometry helps prevent sample loss and supports reproducible results.
- Multiple reinjections: When method development or validation requires reinjecting the same sample several times, total recovery vials help maintain enough volume for repeat runs.
- Trace-level or valuable matrices: When sample is expensive or difficult to replace, minimizing residual volume reduces waste.
- If sample volume is limited or you need repeat injections, choose a high recovery (total recovery) vial.
- If sample volume is not limited and you only inject once, a standard vial may be sufficient.
An Overview of High Recovery (Total Recovery) Vials
Unlike standard 2 mL autosampler vials, high recovery vials feature a tapered conical bottom that allows the autosampler needle to access nearly all of the sample. Most have a total capacity of approximately 1.5 mL, but their internal geometry on the bottom taper minimizes residual volume and reduces sample waste.
These vials are ideal for:
- Low-volume biological or pharmaceutical samples
- Reinjection workflows in method validation
- Analyses requiring complete sample transfer with minimal loss
Where to Buy Total Recovery Vials
Certain HPLC systems require specific high recovery vial designs that differ from standard autosampler vials or vial-insert configurations. Many chromatographers assume these vials can only be purchased from the instrument manufacturer—often at a premium price. Chrom Tech offers a cost-effective alternative.
Chrom Tech works with many high-throughput laboratories to supply high recovery autosampler vials that provide the same performance and compatibility as OEM options but at a fraction of the cost. This helps laboratories maintain consistent analytical quality while controlling consumable spend.
Chrom Tech’s total recovery vials are compatible with many popular HPLC autosamplers. If you need help confirming fit, our specialists can recommend the correct configuration for your workflow.
