Additional Information
Symmetry Shield RP18 Sentry Guard Cartridge, 100Å, 5 µm, 3.9 mm X 20 mm, 2/pk Use the Symmetry Shield RP18 Sentry Guard Cartridge to increase the lifespan of the column. Between the injector and the analytical column is a guard cartridge, a piece of safety lab equipment. The lab equipment functions by limiting the entry of contaminating chemicals and suspended particles into the analytical column. The Symmetry Shield RP18 Sentry Guard Cartridge is made with the same high-performance packing materials that are used in the construction of all Waters analytical columns. The lab equipment was designed and built specifically for situations when a better capacity for biological fluid purification and/or temperature control is needed. Like other Waters products, the Symmetry Shield RP18 Sentry Guard Cartridge is produced in a cGMP, ISO 9001-certified facility utilizing ultra-pure chemicals. Additionally, the Symmetry Shield RP18 Sentry Guard Cartridge packaging material is subjected to chromatographic testing for each batch employing neutral, acidic, and basic analytes. In order to guarantee consistently excellent, repeatable performance, the findings are once again subjected to the highest standards and the narrowest specification ranges.
