What diameter are the tubes, and will they stand up in a test tube holder with 16mm holes?

The replacements are the same size as the originals so will go within the holder

Is there a stand to buy for these vials. I can’t see one on Amazon as the holes are too big for the vials.

Don't really know to be honest. Sorry

You will get a pack of 24 tubes with caps
