Glass columns and Adsorbents

Glass columns and kits for low pressure flash chromatography 
 
Features
  1. Economic low-tech method for the synthesis laboratory
    Suited for the separation of compounds up to gram levels
    No expensive equipment required
  2. MN flash chromatography kits include a glass column, eluent reservoir, silica 60 and accessories.
    Glass columns of different sizes and accessories can be ordered separately.
    These columns are normally filled to a height of about 15 cm, working pressures are 1.5 to 2 bar.
    The most used adsorbent is silica 60 with particle size 40–63 μm, however, you may also use our ranges of other LC adsorbents and POLYGOPREP silica phases.
    Particle sizes < 25 μm should only be used with very low-viscosity mobile phases, because otherwise flow rates will be very low.
    These columns are to be packed by the user.
