Liquid & Slurry Solid & Powder SENTRY RC-200 RESIN COLUMN SENTRY RC-400 RESIN COLUMN Cation Exchange Resin Columns Steam & Water SAMPLE CONDITIONING The Sentry® RC-200 and RC-400 refillable ion exchange resin columns make resin replacement easy and economical, minimizing channeling and achieving a higher resin efficiency than competitive columns with inefficient column diameters. MODELS RC-200 RC-400 BENEFITS The RC-200 and RC-400 refillable ion exchange resin columns are designed to minimize the column's dead volume, assuring highly representative sampling, and meet the demands of special applications, such as the need for large volumes of resin to extend the time between resin replacement or regeneration. The resin columns have removable caps at both ends of the column to assist in refilling or regeneration of the resin. Additionally, porous discs are installed at both ends to contain the resin, assist in flow distribution and reduce channeling. FEATURES ■ Refillable, clear plastic column makes resin replacement economical and easy ■ Provides optimum fluid velocity with increased resin efficiency ■ Designed especially for flow rates common to water chemistry analyzers ■ Minimizes lag time required to detect chemical upset ■ No PVC used; wetted materials will not leach chlorides or plasticizers ■ End fittings are 1/8-inch quick disconnects Sample.
