I would think a better fix to be a CETAC ASX510 autosampler. Easily
holds 360 samples in 7mL tubes, with 10 standards in 50mL tubes.
It comes ready to run on the Optima (I assume that's what you're using)
and the standard PE software also supports it, at least partially for
now. It costs less and does much more (at least they will do more once
PE finishes their software 'fixes'). They are also very durable, and the
support from CETAC has been quite good in the past. The consumables are
also minimal and relatively inexpensive.
It also supplies the user with a very broad variety of rack sizes, the
option of mixing different rack sizes on a single sampler configuration,
and the capability of defining custom racks. Again, though, these
features are not yet fully realized when run under the current PE Optima
software. My understanding is that PE is trying to address these
deficiencies now, but I have absolutely no idea when they might actually
And I do not get commissions.
