2ml ND9 Screw Vial

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.

• When it comes to vial material, glass is your go-to for sensitive HPLC work. But plastic has its moments too, like when you’re dealing with chemicals that don’t get along with glass, like hydrogen fluoride. 
• Plastic vials are perfect for analyzing heavy metals, water, and proteins, and for capillary electrophoresis (CE) and ion chromatography (IC). 

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:

• Surface treatment: Typically have a silanized or deactivated surface, which reduces the interaction between the vial wall and your sample molecules. This prevents sticking and adsorption, ensuring more of your sample remains available for analysis.
• Vial shape: Some high recovery vials have a conical bottom to concentrate the sample at the bottom, making it easier to extract and inject the entire sample volume.
• Closure design: Certain types might have a special cap liner that further minimizes sample loss through evaporation or interaction with the cap material.

When would you need to use high recovery vials?

• Low-abundance samples: When you have limited sample volume or your analytes are present in trace amounts, maximizing sample recovery is crucial for accurate analysis.
• Sticky analytes: Certain molecules tend to stick to glass surfaces, leading to sample loss. Using high recovery vials helps overcome this issue and improve analysis accuracy.
• Sensitive assays: When your analysis requires accurate quantification of every available sample molecule, even small losses on the vial wall can significantly impact the results. High recovery vials minimize this risk.
• Cost concerns: Repurchase or synthesis of expensive samples can be costly. High recovery vials help prevent the need for resampling by maximizing the available sample for analysis.

Things to consider when using high recovery vials:

• Cost: High recovery vials are typically more expensive than standard vials.
• Compatibility: Ensure the vials are compatible with your autosampler and analytical instrument.
• Storage: Choose appropriate storage conditions based on your sample and vial material.

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.
