Flash cartridges

Often glass columns have manually been packed with silica gel based adsorbents. Column packing is time‑consuming. We speed up the whole purification process by ready‑to‑use prepacked polypropylene cartridges with high pressure stability. Our CHROMABOND Flash cartridges can be used in all common automated flash systems.

Flash cartridges – CHROMABOND Flash for preparative LC

Classic flash glass columns

  • Cost-effective low-tech method for the synthesis laboratory
  • Suitable for the separation of substance quantities up to the gram scale
  • No great equipment effort required
  • Glass columns of different sizes available

We offer flash glass columns as empty columns.

Note: Generally, these columns are filled up to a height of 15 cm, the working pressure is between 1.5 and 2 bar. Silica gel 60 with 40–63 μm particle size is most commonly used, but you can also use other products from our LC adsorbents range as well as our POLYGOPREP silica gels.

Good to know
  • Flash glass columns are also available as flash chromatography kit: each kit contain one glass column, one eluent reservoir, silica gel 60 (packing material) and required accessories.
  • If particle sizes < 25 μm are used in flash glass columns it is recommended to work with mobile phases of very low viscosity only, otherwise the back pressure will be too high.
