SelectCore 96-well plates contain a portfolio of monodispersed PVP/DVB polymer sorbents, which have good aqueous wettability, excellent chemical stability, and high capacity for most acidic, basic, and neutral compounds. They are widely used in catecholamines and metanephrines, hormones, fat-soluble vitamins and other clinical analysis. They are ideal for rapid sample clean-up and analyte enrichment with high throughput and recovery.
