EZ columns
These columns are the standard choice for low- to medium-pressure liquid chromatography with aqueous or mild solvents. The adjustable end pieces make them ideal for method development and packing your own media.
EZ SolventPlus columns
Choose EZ SolventPlus columns when you work with aggressive organic solvents, for example in reversed-phase chromatography. All materials in the fluid path offer maximum chemical resistance (PTFE, borosilicate glass, Chemraz®).
Benchmark Microbore columns
Benchmark Microbore columns are the right choice when you work with small sample volumes or costly reagents. The smaller column volume means you use considerably less solvent and achieve higher sensitivity.
Why choose EZ columns?
Ready to use: EZ columns are supplied fully assembled, including all required tubing, fittings and frits. You can start right away without extra preparation.
Adjustable bed length for maximum flexibility: The ergonomically designed end pieces (plungers) are easy to adjust in height, so you can precisely match the bed length to your packing media with minimal disturbance of the column bed. Ideal for method development.
Reusable and cost-efficient: EZ columns are reusable and can be packed with any media that suits your application. This makes them considerably more economical in the long run than disposable columns.
Inert borosilicate glass with PEEK thread: The glass column bodies give full visibility of the column bed and are chemically inert. The PEEK thread ensures durability and a long service life.
Exceptional chemical resistance with EZ SolventPlus: The EZ SolventPlus version is specially developed for aggressive organic solvents, such as in reversed-phase chromatography. All wetted surfaces consist exclusively of PTFE, borosilicate glass and Chemraz® materials with the highest possible chemical resistance.
Minimal solvent consumption with Benchmark Microbore: Benchmark Microbore columns are designed for small-scale analysis, with greatly reduced solvent consumption and increased sensitivity. Ideal for costly or scarce samples.
