Question
header. 1) What solvent are they shipped in? and 2) Can they be shipped in DMF?

Answer
(1) GF-510 HQ are coming with H2O/CH3OH=70/30.
(2) Sorry, we do not do solvent replacement for the GF columns. The GF columns are designed to have strong tolerant towards solvent replacement, so the customer should easily be able to replace the eluent by themselves: just use slower flow rate (~0.2 mL/min) to replace the eluent.

If the customer is going to use the column only with DMF mobile phase for their analysis, other option will be to use KD-804/805 (Depends on their target MW range, we do not have 2000Å pore size KD column). KD series columns are filled with DMF at shipment. One disadvantage of KD might be that since GF column is packed with smaller particle gel, they may provide higher resolution compared to KD column.
