HPLC Guard Cartridges Bio-Bond C18, 300 Å, 5 µm, 21.2 x 10 mm, 2 pc/PAK

Bio-Bond columns with 300 Å pore silica gel are suitable for analysis of proteins, peptides and biological samples. Meticulous care is given to the quality control of surface smoothness, particle shape, pore structure and pore consistency to ensure uniformity of particle structure and enhanced mechanical strength. A low fine percentage from damaged silica particles strengthens the column bed, leading to low backpressure and enhanced column performance and lifetime. Ultra low active silanol and metal content make perfect symmetrical peaks and avoid protein absorption, thereby ensuring detectable activity for protein sensitive to metal.
