High resolution glass columns

The Glass columns offer highest pressure stability and a wide temperature range, which makes them suitable for most biochromatograpy applications. They can be packed and refilled with any BioFox separation media for your bioseparations and purifications or proteins: affinitiy chromatography, ion-exchange chromatography, immobilized metal ion affinity chromatography (IMAC) and size exclusion chromatography (SEC).

Glass column features:

  • chemically and biologically inert borosilicate glass
  • pressure resistant columns allow for higher flow rates and faster separations
  • glass columns are available in 3 lengths and 3 IDs for a wide range of applications and easy upscaling
  • axial compression and column bed height adjustment via a variable adaptor with integrated quick release lever
  • "Uniform flow" distributor on both adaptors makes reverse flow ("Up / Down Flow") possible
  • thermostatting jacket is resistant to cooling liquid
  • easy to change PEEK and PTFE frits
  • robust, pressure resistant design of funnel and fingertight adaptors for safe handling, ease-of-use and longevity
  • all column components - including the glass column and flexible and fixed adaptors - are also available individually
