MacroDac™ is an excellent alternative to W.R. Grace VYDAC® wide pore C18 chromatography media.

MacroDac C18

MacroDac™ C18 is an excellent alternative to W.R. Grace VYDAC® wide pore C18 chromatography media. MacroDac™ C18 is the ideal medium for high-performance reversed-phase chromatography of proteins, peptides, and other large molecules that had previously been difficult to separate by reversed-phase HPLC procedures. The large pores of the 300Å silica allow polypeptide molecules complete access to the interior of the silica pores. MacroDac™ C18 reversed-phase material consists of octadecyl aliphatic groups bonded to the surface of 300Å pore diameter silica. The unique process by which we manufacture MacroDac™ C18 provides for an HPLC media with very high purity synthetic silica and carefully controlled characteristics. The hydrophobic (reversed) phase is attached to the silica using polyfunctional octadecylchlorosilanes resulting in cross-linking, or polymerization of the hydrophobic phase.

MacroDac™ C4 is an excellent alternative to W.R. Grace VYDAC® wide pore C4 chromatography media. MacroDac™ C4 is the ideal medium for high-performance reversed-phase chromatography of proteins, peptides, and other large molecules that had previously been difficult to separate by reversed-phase HPLC procedures. The large pores of the 300Å silica allow polypeptide molecules complete access to the interior of the silica pores. MacroDac™ C4 reversed-phase material consists of butyl aliphatic groups bonded to the surface of 300Å pore diameter silica. The unique process by which we manufacture MacroDac™ C4 provides for an HPLC media with very high purity synthetic silica and carefully controlled characteristics. The hydrophobic (reversed) phase is attached to the silica using polyfunctional butylchlorosilanes resulting in cross-linking, or polymerization of the hydrophobic phase.
