Strata C18-E SPE Products
Strong Hydrophobic Retention Solid Phase Extraction (SPE)

Strata C18-E is a silica-based end-capped C18 solid phase extraction (SPE) sorbent that offers strong hydrophobic retention with negligible secondary polar interactions from active silanol groups. Strata C18-E can be best used for extraction of hydrophobic or polar organic analytes from aqueous matrices. In addition, Strata SPE sorbents are manufactured with the highest purity and extensively tested to give clean extracts.
