B-Series (Basic)

MODUS B-Series flash columns are manufactured with the same cartridges as the standard series (and therefore have all the same features) but are packed with economical, high-quality silica gel (40-63μm, 60Å) or 50-75μm alumina. The alumina flash columns are particularly useful when the sample is sensitive and prone to degradation on silica gel. B-Series offers great savings for everyday purification.


  • Economical solution for everyday purifications
  • Packed with high-quality silica gel or alumina
  • Unique dry packing technique guarantees high-resolution & reproducibility
  • Available in a variety of sizes
  • Max operating pressure of up to 300psi
  • Luer Lok end fitting for universal compatibility

Chromatography Direct MODUS columns are an excellent alternative to other flash columns available offering fast, easy purification and scale-up.

Resolution and Reproducibility
MODUS B-Series (Basic Series) cartridges are manufactured using an innovative dry packing technique resulting in higher resolution and reproducibility. Featuring the industry standard Luer®-Lok end fitting, MODUS B-Series allow for quick, easy connection to most flash chromatography systems including ISCO, Biotage, Yamazen, Teledyne ISCO, Analogix (Varian), Interchim, Grace, Armen and BUCHI. All MODUS columns and media pass through rigorous QC testing which has resulted in an industry leading quality consistency of media for over 10 years.
