Look to us for your radiochemistry testing products. We have what you need for your radioactive isotope separations, actinide precipitations, and sample preparation for alpha particle analysis. Choose from ion exchange columns, a variety of filters for alpha spectroscopy, SPE disks, and scintillation vials. Clarified polypropylene columns are available with or without a frit. With our unique design, the frit is elevated just off the bottom surface of the column by a shoulder that is molded into the column. This gives you a much greater surface area than standard column designs.
