Merck, 67469-U, BIOshell A400 Protein C18 Column

BIOshell 400 Å Protein C18 columns contain 3.4 μm advanced Fused-Core® particles with 400 Å pores that are specifically engineered to provide efficient separation of larger proteins. These columns offer maximum hydrophobicity for resolving tricky hydrophilic and PEGylated proteins. The 3.4 μm Fused-Core particles allow a shorter analysis time yet similar back pressure to fully porous 1.7 μm, 300 Å fully porous C18 particles. These columns can be operated long term at pressures up to 9000 psi (600 bar), temperatures up to 90 °C, and within the pH range of 1 to 9.
