J.T.Baker® BAKERBOND®, SPE 96-Well Plates

Proveedor: Avantor
Descripción: Solid Phase Extraction (SPE) is commonly used as a highly selective sample clean-up or sample enrichment method prior to subsequent analyses. J.T.Baker® BAKERBOND® SPE 96 well plates are well suited for high throughput and automated SPE methods. With complementary high capacity sorbents to existing spe extraction columns in the J.T.Baker® BAKERBOND® range, higher throughput methodologies can now be simply developed and automated.
