I was buying some bottles and noticed an item called "injection vials". From the thumbnail, they looked like ordinary little vials, and it was $3 for
a pack of 30, so why not? When they arrived I was completely stumped for what purpose they could be used for. Anyone know what they are used for, and
maybe a more specific name for them?
I've added a picture, yes the bottom is open and the pencil is inside the vial, and there is an inverted cone attached to the base of the opening from
the top.

They're reduced volume while retaining a conic bottom for autosamplers. The top lip is designed for a septa to be crimped on with an aluminium
sleeve.

I have never seen one quite that small, but yes they are ultra small volume auto-sampler vials for an HPLC or GC system. The normal sized ones are
2ml, and have bottoms. I have seen inserts for those that hold 200 or 100 ul, but that looks like one for about 20 ul.

Ah, sweet! Well now I know what they are even though it is unlikely I can ever use them for anything. Maybe as a desk decor?
