Arabidopsis gas exchange chamber. a Schematic overview of the three lid-types and the chamber. The chamber body contains two stabilizing units (1 + 2) and a rubber lip and foam gasket (3) to allow for an air-tight assembly. The two units are connected via screws (4) and closed by a lid. Air is flowing via an inlet (5) into the chamber and leaves it though an outlet (6). Depending on the lid-type an adapter tube (7) is added to the inlet. b Pictures of the gas exchange chamber filled with Arabidopsis thaliana, Mesembryanthemum crystallinum and Lotus japonicus
