Check gas bottles
Check the pressure of the oxygen (ChemLab), helium and argon bottles (Tween Pallet Stores). Ensure the bottles are above 200 psi; otherwise, swap them out with fresh bottles. When a Pallet Stores bottle array is empty, tear the yellow tags to EMPTY, disconnect the manifold and connect it to full bottles. It is good practice to always have a full gas bottle array ready to go.
