Chromatography Column, Pyrex
Product Code : EL-C-10973
Quick answer: The Chromatography Column, Pyrex is a 300 x 20 mm borosilicate glass column with a porosity 'O' sintered disc to support the packing, a 'Rotaflo' stopcock of 3 mm bore to control the flow, and a 19/26 socket at the top. It is used to separate and purify compounds by column chromatography. Lab Exports supplies it as a reseller to schools, colleges and universities.

How the column chromatography experiment is done
Column chromatography works on the same principle as TLC but on a preparative scale. The column is packed with an adsorbent such as silica gel or alumina (the stationary phase), the mixture is loaded at the top, and a solvent (the eluent) is run through. Components that are held less strongly move down faster and leave the column first, so they can be collected in separate fractions.
The sintered disc at the base holds the packing in place without the plug of cotton wool used in simpler columns, and the stopcock lets the operator set a steady drip rate. Borosilicate glass resists the organic solvents used as eluents.
- Clamp the column vertically and close the stopcock.
- Pour in a slurry of the adsorbent in the eluent and let it settle on the sintered disc, keeping the solvent above the packing.
- Load the sample in a small volume of solvent onto the top of the packing.
- Open the stopcock to a steady flow and keep the column topped up with eluent; a reservoir can be fitted to the 19/26 socket.
- Collect the eluate in numbered fractions and check them by TLC.
