General
ECO columns are glass columns for almost all types of soft gel and low
pressure (pressure limit 5 – 30 bar) liquid chromatography applications.
With a choice of one or two adjustable length plungers, they are available
in two forms: AB (aqueous buffer) for use with aqueous buffers and cold
room applications and SR (solvent resistant) for all forms of normal and
reversed phase chromatography.
ECO columns are produced by high-precision CNC manufacturing. They
are competitively priced and equipped with a screw-lock system which
makes it possible to open and seal the column simply and quickly. Each
column passes a quality control pressure test. A water-jacketed option
can be supplied on request.
