Hi All... On a related note, we have been having problems with a recent batch of exetainer vials purchased from Labco (UK)... The vials are marked as the "new thread" design... About 1 in 10 seem to leak, which sometimes trips the source on the machine... Has anybody else had problems with recently purchased exetainer vials? I think Ill send a short note to the supplier... We've bought >1000 vials from Labco over the past 12 months and never had a problem with leakage... Our old beast of a machine (MAT 252) and GasBench are working fine... Any insights would be appreciated...
