These general purpose columns can be used for gravity or flash chromatography. Each has a Teflon® stopcock and a Rodaviss® top outer joint. The column is constructed using medium wall tubing for extra durability. Glass wool (not supplied) is used to support the column packing. The lower end of the column has a round bottom. Connections between the column, reservoir and flow control adapter are made using Rodaviss® joints which afford a grease free seal while holding glassware together without additional clamps.
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 24 inches (20.3 to 61.0 cm). Smaller bore columns have a 24/40 joint while larger columns (2.5 and 3.0 inch diameter) have a 45/50 joint.
Additional sizes are available by special order. All columns are also available with an optional clear plastic coating (temperature range -20 to 140 °F) by special order.
The effective length listed in the product selection Size menu is the length of the the full-width column above the stopcock.
Similar columns with joints and/or packing support frits are also available. See our Chromatography Page.
