Delta-Pak C4 Guard Column, 300Å, 5 µm, 3.9 mm X 20 mm, 1K - 30K, 2/pk

Delta-Pak packings are based on a highly stable, bonded, end-capped 5m or 15m spherical silica that is ideal for the separation of peptides, proteins, and natural products. Delta-Pak is available in two pore sizes (100 and 300) with either a C4 or a C18 bonded phase. Delta-Pak packings are available in a variety of cartridge and column configurations, allowing for consistent and predictable milligram-to-gram scale purification. You can also easily check the purity of your fractions by having the same chemistry available on a high-efficiency 5m particle. The 15 m packing is available in analytical-scale dimensions for preliminary preparative chromatographic analysis, peptide mapping, and fraction-purity testing. Particle size has no effect on the chemical properties of the packing materials.
