Pre-packed OptioBio™ 40Q 10x100 glass columns are designed for small-scale purification as well as screening and optimization in bioprocess development and scale-up.

  • Pre-packed for reliable and reproducible results
  • Optimal for high-performance small-scale purification and method optimization in bioprocess development
  • High throughput and purity


OptioBio 40Q 10x100 column is pre-packed with WorkBeads™ 40Q resin for ion exchange chromatography (IEX). The resin is designed for research and industrial scale purification of proteins, peptides and nucleic acids and utilise the difference in their surface charge. WorkBeads 40Q is a strong anion exchange resin with quaternary amine ligands. WorkBeads are agarose based chromatographic resins manufactured using a proprietary method that results in porous beads with a tight size distribution and high mechanical stability. WorkBeads resins are designed for separations that require optimal capacity and purity.

Storage 2 to 25 °C in 20% ethanol
¹. The median particle size of the cumulative volume distribution.

². Dynamic binding capacity determined in 20 mM Na-citrate, pH 4.0, at a flow of 2 ml/min (150 cm/h; 4 minutes residence time).
³. Dynamic binding capacity determined in SO mM Tris-HCI, 50 mM NaCI, pH 8.0, at a flow of 2 ml/min (150 cm/h; 4 minutes residence time).
⁴. Maximum flow rate for aqueous buffers at 20 oc. Decrease the maximum flow rate if the liquid has a higher viscosity. Higher viscosities can be caused by low temperature.
Use half of the maximum flow rate for 20% ethanol
