Bio-Rad Macro-Prep 25 S Media - Manual (Page 4)

Fig. 1. Linear flow rate vs. operating pressure. The Macro-Prep 25 S support was evaluated for
linear flow rate vs. operating pressure by measuring the pressure at a series of flow rates using 1 M NaCl
on a 1.6 cm (ID) x 12.5 cm (H) column. The pressure plotted was determined by subtracting the pressure
generated by the column when empty from the pressure generated from the column when packed.
The Macro-Prep 25 ion exchange supports are available as the Macro-Prep 25 S
strong cation exchanger and the Macro-Prep 25 Q strong anion exchanger.
Table 1 lists the properties of these supports.
