Dear Newsgroupers,
Thanks to those who replied , although there were only 2 I have included
them with this follow up posting. Looks to me like its time that they
fixed this problem.
Sincerely,

David,
We used to have three tetrads and all had problems that I would
consider severe. Apparently, the Alpha units do not have
proper sealing for the block area and when the units are run
for an extended period of time at 4 C, condensation builds up,
drips into the Alpha or the base and causes shorts and blown
fuses. We ended up sending all three Tetrads back and getting
PTC-100 cyclers on a semi-permanent basis until the Tetrad
problem is permanently fixed. The PTC-100 units work fine (so
far). I know of at least one other lab that has done this as
well.

Hi David,
I have one Tetrad at the moment with 2 ordered. I have had it for almost a
year and love it.
I use it for sequencing for a high-through put sequencing project and am
keeping 3 X 377's
busy with 3 -4 gels a day per machine at 48 lanes using ET-primers from
Amersham. I have had
some problems with fuses blowing due to running them at 4C for long
periods
but they are
easy to replace manually.
Hope this helps,
Christiane
