Resprep Polymeric SPE Cartridges and 96-Well Plates (Reversed-Phase mode, Ion-Exchange mode)

Silica-free, bonded polymeric material—no unwanted secondary silica interactions, even with basic compounds.
High surface area—higher loading capacity compared to silica-based sorbents.
Stable over a wide pH range (0–14)—won’t hydrolyze under extreme conditions.
Water-wettable—streamlined conditioning and equilibration steps drastically reduce solvent usage and sample prep time.
No flow-rate dependence—maintains retention and capacity after conditioning, even if dried out from vacuum or positive pressure flows.
Choose cartridges for high loading capacity; 96-well plates for high throughput and automation.
