Strata Basic Screen SPE Products

Mixed-Mode Sorbent Solid Phase Extraction (SPE)

Improved recovery of basic drugs from biologic samples in a funnel shaped tube ideal for large sample volumes with minimal extraction solvent. Small bed mass requires only minimal extraction solvents for more concentrated extracts by incorporating the hydrophobic selectivity of a C8 phase and strong cation-exchange.

Available Formats

Large Reservoir Cartridges (LRC)

General Starting Method

Strata Tube

Strata Screen-C Strong Cation-Exchange

1 mL Methanol
1 mL Water
