SPE Cartridges CHROMAFIX ® HR-XA, 0.8 ml, Medium

Configured for stable performance in synthesis settings, the Spe Cartridges Chromafix® Hr-Xa, 0.8 Ml, Medium, fall under the ion exchangers for the SPE category. These cartridges, made from PP columns with PE filter elements, are particularly suitable for the solid phase extraction of small sample volumes. They feature a female Luer fitting at the inlet and a male Luer tip as the exit, making them compatible with various lab equipment. The Hr-Xa version, specifically, is a medium particle size, hydrophobic, mixed mode anion exchanger (MAX), ideal for acidic active ingredients from strongly matrix-contaminated samples such as urine, plasma, or serum.
