Designed to integrate seamlessly into laboratory operations, the Polypropylene Columns Chromabond Xtr, available in volumes ranging from 70 ml, are ideal for liquid-liquid extraction (SLE). These columns, featuring a kieselguhr phase, are particularly suited for the extraction of analytes from aqueous to an organic phase. They offer advantages such as fast, reproducible, and economical separations, while also ensuring high recovery rates and saving time and solvents. The columns' large pore size, high pore volume, and consistently high batch-to-batch quality make them versatile for various applications, including clinical chemistry, dyes in textiles, environmental and food analysis, and physiological fluids like blood, plasma, and serum.
