Bond Elut Plexa, 96 round-well plate, 1 mL, 10 mg, 1/pk. Bond Elut Plexa offers easy-to-use methods for general purpose extraction. A unique polymeric architecture with a nonretentive, hydroxylated, amide-free surface, and a nonpolar PS-DVB core retains small molecules. Binding of proteins and lipids on the polymer surface is minimized, giving cleaner samples and reduced ion suppression.;Plexa is ideal for high-throughput assays requiring validated performance with minimal method development. The standard nonpolar retention mechanism is applicable to almost any analyte type. Plexa Polymeric SPE is also available in ion exchange SPE formats, Plexa PCX SPE for cation exchange, and Plexa PAX for anion exchange.
