YMC ECOPlus Glass Columns

Glass Columns for Higher Pressure Applications

ECOPLUS glass columns are multi-purpose columns for almost all types of liquid chromatography applications (pressure limit 30 – 80bar). They are available in two forms: AB (aqueous buffer) for aqueous buffer and cold room applications and SR (solvent resistant) for normal- and reversed-phase chromatography.  Adjustable length plungers at both ends and a totally inert triple chevron sealing system (SR versions) support the complete spectrum of applications from classical normal-phase and reversed-phase chromatography right through to biochromatography.   The Quick-Lock connection system makes it possible to open and seal the column simply and quickly.
