I was wondering

If I mix and make my own gear from powder, how do I go about sealing vials, if its even possible.

Basically

Does anyone know of a good site that has glassware (empty) and/or info about sealing VIALS at home, since I'd want to make single use vials that I can take with me when travelling. IF not, where do I find the bottles and caps!

I hope Im being clear.
