Cole-Parmer Diba Omnifit EZ Chromatography Column w/ 2 Adjustable Endpieces, 5 x 250 mm; 1/ea
Ergonomically designed EZ columns are easy to use yet provide excellent results. Columns are ideal for low- to medium-pressure applications and are resistant to many solvents used in liquid chromatography. Modular design gives you the flexibility to mix and match column sizes with different endpiece types to meet your specific requirements. Two adjustable endpieces (plungers) provide maximum flexibility in bed height. With an adjustable endpiece at both ends of the column, you gain 160 mm of adjustment plus the ability to make fine adjustments with minimal disturbance to the packed bed. Each glass column assembly is supplied preassembled with 25 m PE frits and comes with all the tubing, fittings, and connections you need to get started.
