Column Extenders are used to join two columns of the same diameter to form one longer column. The inner bore of the column extender matches that of the columns so that there is a minimal disruption of the bed at the extender.
To use a column extender to join 2 columns, simply remove the lower end plate from the upper column and the upper end plate from the lower column. The column extender is threaded on both and and simply screws into the places previously occupied by the endplates. Using this method you can join as many column bodies as desired into a single interior bore, but since column bodies as long as 100 cm are available in every diameter, ceiling height usually limits you to 2 or 3 bodies.
The column extender is a wetted part of any system in which it is used. Because of this they are available in 2 different materials: polypropylene for use with aqueous solvents and PTFE for use with organic solvents.
Column extenders can also be used to connect a packing reservoir to a column. This lets you cleanly back a column with minimal bed disruption without the need for excessive ceiling clearance.
