Hi Zach and other Fluorine-Fans,
we are in a good position in Germany it seems; we have no problems in getting high quality fluorine
for a very reasonable price. About 1 kg F2-gas from SOLVEY - FLUOR UND DERIVATE GmbH,
Carl Ulrich Str. 34
D-74206 Bad Wimpfen
Tel: +49 7063 510
Whether they export their stuff to U.S. I dont know. It might be problematic.
An other possibility is FLUOROGAS in England. See: www.fluorogas.co.uk
