Features of RSpak DE Series (4) (Reproducibility between Production Lots)

The production of packing materials for RSpak DE-413 is done in single stage, and, that of ODS columns is done in two stages, production of base material and bonding of C18 group. The simple production process of DE series ensures good reproducibility between production lots.
