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

Primarily used for legacy methods. If you are developing a new method, please consider our newer technology, BioResolve RP mAb Polyphenyl, XBridge Premier Protein BEH C4, or ACQUITY Premier Protein BEH C4 Columns for superior separation, speed, sensitivity, and resolution.

Delta-Pak packings are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
