Cole-Parmer Diba Omnifit EZ Chromatography Column w/ 2 Adjustable Endpieces, 5 x 150 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. Columns come with two adjustable endpieces pre-assembled with 25 m PE frits. Each adjustable endpiece gives you the flexibility to modify the bed length up to 80 mm in height plus the ability to make fine adjustments while causing minimal disturbance to the packed bed. Columns are supplied assembled and ready to use, with all the tubing, fittings, and connections needed to get started.
