ZEOsphere phases are fully porous silica gels in spherical shape. ZEOsphere DRP Mixed-Mode silica gels are reversed phase chromatography gels, merged with different amounts of strong Anion exchanger (A) or strong Cation exchanger (C). Both ionic and hydrophobic functionalities on the same surface increase significantly the performance compared to conventional chromatographic phases like Reversed Phase. ZEOsphere DRP can substantial increase the recovery/yield while decreasing the organic solvent consumption. ZEOsphere DRP Mixed-Mode phases are used for the purification charged molecules like peptides, insulins(analogues) and oligonucleotides.

ZEOsphere DRP Mixed-Mode are available in multiple pore and particle sizes.

Bonded ZEOsphere products are consistently produced and controlled according to quality standard ISO-9001. Strict QC controls from raw material to finished product ensure high lot-to-lot reproducibility and tightly controlled specifications.

ZEOsphere silicas are available in different quantities with a wide variety of packing sizes to meet individual applications and economic requirements.
