ordering
note
We strongly recommend ordering a semi-prep
or prep column only after evaluating the desired
separation on an equivalent analytical-scale
column. Because we cannot re-use a column or
the silica it contains once it has left our facility,
we cannot accept returns of large-scale columns
(except in cases of our error).
Supersize without
surprise!
