The reservoirs range in capacity from 100 to 2,000 mL.

This series of columns is available with inner diameters of 0.5 to 3.0 inches (13 to 75 mm) and lengths from 8 to 18 inches (20.3 to 45.7 cm). For additional sizes not listed below, please inquire. All columns are available with an optional clear plastic coating (temperature range -20 to 140 °F) by special order. Optional flow controllers (CG-1201) are available for flash chromatography use.
