X23A2 Hutch Ventilation
The on/off switch for the ventilation is near the entrance to the X23A3 hutch (for some reason...).
The ventilation tube in the X23A2 tube can be articulated to move to any convenient position. Usually it is stashed up near the ceiling. For most experiments involving low flows of common gases (O2, N2/H2, and so on), that position supplies adequate ventilation. If possible, it is a nice idea to extend the outlet of the experimental gas exhaust up to the ceiling near the inlet of the ventilation tube.
