Low to Medium Pressure LC Columns
Chemglass Life Sciences Column, Chromatography, 24/40 Outer Joint, 500mL Reservoir, 1 1/2in ID X 18in E.L., 2mm Stpk
Column, Chromatography, 24/40 Outer Joint, 500mL Reservoir, 1 1/2in ID X 18in E.L., 2mm Stopcock. General purpose column having a PTFE stopcock, reservoir of the listed capacity and a top standard taper outer joint. Glass wool (not supplied) is used to support the column packing. Column is constructed using MEDIUM WALL TUBING. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC CHEMISTRY 43, 2923 [1978], and covered in U.S. Patent Number 4,293,422 dated October 6, 1981) when used with CG-1191 flow control adapter. Lower end of the column has a round bottom.
Teledyne ISCO, Inc RediSep Rf Gold C18Aq, 50 g
RediSep Rf Gold C18Aq is specifically designed for highly aqueous conditions. Monofunctionalized C18 bonding is interspersed with hydrophilic ligands to prevent phase collapse in high aqueous conditions. RediSep Rf Gold C18Aq should be used in separations requiring 0–50% organic. These columns offer increased retention through increased polar interactions and the ability to use weaker solvent system. This is usefulfor highly polar, water soluble compounds such as dyes, glycopeptides, and nucleotides.
Chemglass Life Sciences Column, Chromatography, 45/50 Outer Joint, 3in ID X 24in E.L., 4mm Stpk
Column, Chromatography, 45/50 Outer Joint, 3in ID X 24in E.L., 4mm Stopcock. Similar to CG-1188 but with a sealed in COARSE porosity fritted disc to support column packing. Column is constructed using MEDIUM WALL TUBING. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC CHEMISTRY 43, 2923 (1978), and covered in U.S. Patent Number 4,293,422 dated October 6, 1981) when used with optional CG-1191 flow controller and CG-1190 reservoir.
