Dear Arnold, Steve and to all other Isocarb users,

are you really sure about the reason for the sample spillage out of the
boats? The discription of your problem sounds like it might be different. I
made the experience concering this or a slightly different problem that an
abrupt initial evacuation of the carrousel was the reason for powder on the
bottom plate. We solved the spillage problem by exchanging to a longer
evacuation capillary.
By the way, does anybody know the secrets to produce a good reproducibility
for small (cold finger) samples in Isocarb-Optima combination?
