EZ Columns

The simplified design of our EZ chromatography columns combines reliable column performance with easier use for fast protein liquid chromatography (FPLC) and low-pressure liquid chromatography (LPLC) applications. The redesigned columns provide improved ergonomics for simpler height adjustment, anti-roll features, improved endpieces for easier assembly, and superior frit placement for even distribution of sample flow. Made from high-quality materials, the system provides optimal chromatography performance through precision borosilicate glass columns for visual clarity, PTFE endpieces and plungers for a secure seal, PEEK threaded ends that won’t chip or break, and dual O-rings to ensure a secure seal. Our standard EZ columns are designed to suit the majority of standard laboratory chromatography applications, while the EZ SolventPlus columns are designed for maximum chemical compatibility in applications using organic solvents, such as reverse phase chromatography. Both EZ column styles are available in a variety of sizes and multiple fixed or adjustable endpiece configurations.

EZS Columns

Use these EZ SolventPlus™ columns for techniques using organic solvents such as reversed phase chromatography. EZ SolventPlus columns have only the most chemically inert materials in the fluid path—borosilicate glass, PTFE, and Chemraz®—ensuring the utmost chemical resistance. 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 30 μm PTFE frits and comes with all the tubing, fittings, and connections you need to get started.

Microbore Columns

Microbore columns are designed for applications requiring the smallest bed volumes with resistance to aqueous solutions and most solvents used in liquid chromatography. With fixed, nonadjustable endpieces, microbore columns are ideal for low-pressure or gravity feed systems and are available in a variety of lengths. · Internal diameter of 3 mm · Column length range between 25-150 mm · PCTFE endpieces accept 1/4”-28 UNF threaded fittings to connect column in-line · PCTFE and stainless steel frits provide superior bed support · FKM/FMP O-rings provide secondary backup seal
