Waters Alumina N Plus Long Dbl. Luer-Lock CRTG, 50/p ;WATBGN-WAT020510DL

Waters Alumina N Plus Long cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. These versatile Plus Long cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems. - WATBGN (Additional S&H or Hazmat Fees May Apply)
