Autosampler Vials & Closures

How do you choose the right autosampler vials and closures? There are 4 steps manufacturers universally agree will help you get to the right product.

Start with the closures

Screw thread closures are widely used for HPLC and LCMS. They’re easy, straightforward, and don’t require any special tools to use. They provide a better seal than snap tops, and are preferred when volatile solvents are involved.

Snap tops are a choice of convenience. If hundreds of samples need capping at once, it’s fast and easy. And if the diluent/solvent is water near room temperature, the snap top is just fine.

If your instrument requires a magnetic seal, crimp closures/caps are required.

*Hot tip - to reduce or eliminate problems making a proper seal, use an adjustable crimper.

Find your vial material

As you know, borosilicate glass is the least reactive. It's the most common type of autosampler vial.


Polypropylene vials give you a good cost control option in certain circumstances - working with acetone, ethyl acetate, methanol, isobutyl alcohol, and methyl ethyl ketone.

Pick your size

Most autosampler vials are 2ml.


Vial inserts like these can reduce that volume as needed.

Amber or clear?

Like anywhere else in the lab, amber glass is suitable for light sensitive samples.


For everything else, clear is the standard.
