Samples are moved into a glovebox via an antechamber. To remove all adsorbed water or oxygen from the sample, it is first loaded into the antechamber, which is subsequently evacuated to a low vacuum state. After some time has passed, the antechamber is refilled with an inert gas, and the process is repeated 3 times. This procedure may be insufficient for highly porous media such as Kim-wipes. In this case, the sample should be placed in a vacuum oven overnight before transfer into a glovebox.
