The adapter is used to attach 1/8″ or 1/16″ tubing to a conventional glass columns.
The adapter works by squeezing a flexible O-ring over a glass column outlet.
Because there is no standard size for outlet diameters, three different sizes of O-rings are provided with the adapter. Only one most suitable O-ring should be used at any given time. Extra rings may be placed onto the adapter outer surface for storage (see photo).
Two kinds of O-rings are provided:
To prolong useful life span of the O-rings, the adapter should not be stored attached to a column soaked with solvents. It is a good practice to rinse the adapter with an appropriate solvent and store it in a dry place.
For most glass columns, 1/8″ tubing is recommended to minimize the hydrodynamic resistance to liquid flow. 1/16″ tubing should be used only for very small glass columns (less than 10 ml volume) to minimize the dead volume of the system.
