Hi Bernd,

Sorry, I didn't realise you were looking for vials for carbonates
rather than waters.  The vials I've been using for carbonates with
the conical inside are from Wheaton (http://www.wheatonsci.com/),
catalogue #986284.  As for septa, there's a good selection of septa
available from Supelco (via the www.sigma-aldrich.com web site).
However, I'm not sure where to get PCTFE discs - but maybe
teflon-faced septa (available from Supelco) would do the trick?  (I
haven't had chance to try these yet)

Cheers,
Simon
