HYDROCELL RP 5D is produced from macroporous PS-DVB beads with particle size 5 µm and 10 µm (d₅₀) respectively. These particles have high pore volume and permeability. Their major advantages are lower back pressure and higher permeability in the operation. These media reduce the fluctuation and drop of back pressure when it was used in the gradient separations.

RP 5D is prepared from 5 µm and 10 µm (d₅₀), 1500 Å spherical PS-DVB particles. The media provide optimum pore volume and large pore size with increasing permeability and high separating efficiency for large proteins, polypeptides, oligonucleotides and other macromolecules.
