Our standard aqueous series columns have glass bodies and black polypropylene endplates. They are useful when using aqueous solvents, if you need to use organic solvents we recommend that you try our Organic Series Columns.

The wetted materials in these columns include glass, nylon, polypropylene, and nitrile rubber. They can be used at temperatures from 0 to 80°C.

Each column is complete with the glass body, upper and lower endplates, and tubing fittings. The 2.5 cm diameter and smaller columns ship from stock with fittings for 3/16" (4.8 mm) OD tubing and the 7.5 cm diameter and larger columns ship from stock with fittings for 1/4" (6.3 mm) OD tubing. The shorter 5 cm diameter columns ship from stock with the 3/16" OD tubing fittings and the longer 5 cm diameter columns ship from stock with the 1/4" OD tubing fittings. If you desire a different size tubing fitting we can normally substitute the fittings at no charge if the request is made before the order is placed.
