i know this is very specific post but does anyone know of a reliable source of 100ul HPLC vials.. i cant seem to find anyone uk based that ships immediatly.. !?

Try Alltech. They might have some.

Company website has changed since I was last on....

Ive had 300ul crimp top ones off them many times and they were pretty good. US based but despatched from Lancs pretty sharpish. Youll have to check and see if they do 100ul ones though.

thanks

Chromacol do the 300ul tapered vials:

They are usually very quick to ship.

Ooh, just looked a bit further down that same page (MicroVials) and they have some 100ul too.
