About the Vacuum Box System
Eichrom continues its tradition of being your “time saver” by introducing its Vacuum Box System and extraction cartridge line. By employing vacuum in our already advanced separation methods, analysis time can easily be cut in half over traditional gravity flow Eichrom columns. Customer comments and research in our Rad-lab indicate the same consistently high yields for actinides and strontium as with our conventional columns. Chromatography is improved with the new cartridges that use our smaller S-grade resin beads. Another advantage of the cartridge design is the ability to stack two or more cartridges together for tandem separations. Many of our separation procedures use a common load solution that passes through multiple resins, for example TEVA, TRU and Sr Resins. Using the Luer connections, the cartridges can be easily stacked during sample loading and initial rinse steps and then be separated for final analyte stripping. For sample loading onto our cartridges, a standard syringe barrel is recommended, although many reservoirs with a male Luer connection can be used. The cartridges are connected to the vacuum box by two disposable plastic parts. The white inner tube provides an excellent seal with the cartridge and the yellow outer tip provides support. As with our columns, each cartridge is labeled with an identifying lot number. Most Eichrom Resins are packaged in cartridges and are currently in stock.
