we also have a GVI MultiFlow system and we buy our caps and septa for the glas vials here in Germany at Klaus Ziemer GmbH, Am Parir 27, D-52379 Langerwehe, phone: +49 2423/40493-5, fax: +49 2423/40493-88, e-mail: [log in to unmask] After use we replace only the septa.
I hope this helps.

Betreff: Re: [ISOGEOCHEM] septa for exetainer vials
Some years ago I went through the same inquiry, as we were using upwards of 200 caps/septa a day.
The Labco septa are a larger size than most precut HPLC or GC septa. We tried the largest smaller septa--NO GO, the needle punches them through most of the time.
I sort of remember discussing this with the director of Labco: he told me that they purchased septum material in sheets and cut it themselves. This is too time consuming to do by hand (leather shops will sell you the right hand punches). Bel-Art is a manufacturer of septum materials in the USA and will sell sheets. Good luck in finding a couple of elves...
I consoled my environmental guilt by using a bleach rinse and using the recycling bins. Five years on I guess it's the same old mindset at Labco.
