Sepax HPLC Guard Cartridge, with Holder, GP-C18, 120 Å, 5 μm, 4 x 10 mm

GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
