Strata C18-E SPE Solid Phase Extraction (SPE)

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 the 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.

Strata C18-E is compatible with various formats, including C18 SPE cartridges. Our C18 SPE products are synonymous with quality, offering the highest purity and undergo rigorous testing to deliver consistently clean extracts for your analytical needs.
