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. One fixed endpiece is used as a bed support and one adjustable endpiece (plunger) lets you increase the bed height up to 80 mm, plus gives you the ability to make fine adjustments with minimal disturbance to the packed bed. Each glass column assembly is supplied preassembled with 25 μm PE frits and comes with all the tubing, fittings, and connections you need to get started.
