Hi! While on the subject of carbonate analysis by GVI's Multiflow/Multiprep, can you suggest a suitable conical-shaped vial? Our Multiflow uses a Gilson 222 autosampler. Original vials for the heated block were Labco's 54x12.5 mm x 3.7 ml Exetainers, but these are flat-bottomed. I cannot find an equivalent conical/rounded/v-shaped vial at Labco's web page, or for that matter at any other manufacturer's web page (and we have attempted a few!). Where do you get your vials? Has anybody tested the posibility of using a conical insert in a flat Exetainer? Cheers, Clemente
