We
manufacture glass chromatography columns in every possible
size and configuration. Chromatography columns are as various
as chemists: long & skinny,
long
& fat, short & fat, short & skinny, with a reservoir
and without, with a frit and without. And then come the choices
of joints... Your choice will depend on the compounds you
want to separate, the quantities, and your personal predilections...
We make our chromatography columns to your specifications. We can also alter
existing columns to meet your needs, although this is not always cost effective.

gallery. |

We
describe custom glass chromatography columns from the top down:
see a sketch here.
For more information on specifications, see our Chromatography Column Specifications.
We like to provide fritted filters in your columns that work
best for you. Many manufacturers use coarse or medium frits,
corresponding to pore
sizes of 40 - 60 µm and 10 - 16 µm. We have
found that the European size designated P3 to be best for
most column usage; its pore size is between coarse and medium:
16 - 40 µm.
Since column packings are frequently called out with a particle
size of 40µm, this porosity of frit holds up the packing
well, but allows for good flow.
We also manufacture flow control adapters, separable solvent
reservoirs, and solvent addition funnels.
