Swagelok cell instructions

> Swagelok cell instructions

These are instructions for putting together the Swagelok Cell.

The following instructions can be used for either 2 or 3 probe configurations of the Swagelok cell. Procedure may need to be adjusted if being done within the glovebox for air-free testing.

    1. Make sure to clean the cell components thoroughly before use.
    2. Prepare your cell materials (anode, cathode, separator, electrolyte).
    3. The inside diameter of the cell is 3/8”, so anode, cathode, and separator should all be smaller in diameter with the separator being the largest.
    4. If using a soft metal (lithium or sodium) as the anode, follow these steps:
      1. Cover the metal with plastic film and roll out the metal using the roller to as thin as possible.
      2. Punch out the metal using the 3/8” steel punch.
      3. Carefully press the metal disc into the stainless steel puck.
      4. Use a razor to clean up any excess metal.
      5. Cover loosely with a plastic until ready to use.
    5. Insert the long stainless steel rod into the T-cell and attached sealing rings and tighten the nut.
    6. Carefully hold the cell vertically with the inserted rod side down.
    7. Place the cathode with the active side up in the center of the flat area of the rod.
    8. Place the separator on top of the cathode. Be sure to not move the cathode out of position.
    9. Place the anode with the active side down. Drop the stainless steel puck on top the anode.
    10. Add the conical spring to the stack and insert the shorter steel rod in the cell behind the spring.
    11. Attach the sealing rings and tighten the nut while applying pressure to compress the spring.
    12. Rotate the cell so the open end is up, and add electrolyte to the open end of the Swagelok cell.
    13. While holding the long rod in place, slightly loosen the long rod nut, and slowly release the pressure. Electrolyte should fill the area by the conical spring. Carefully tap the cell to release any air bubbles.
    14. Compress the spring by pushing the long rod in again, and tighten the nut.
    15. Fill the rest of the cell with electrolyte so that the fill level in slightly into the unsealed end. Tap the cell to release any bubbles.
    16. Insert your preferred plastic rod. Solid for 2-probe and hollow for 3-probe.
    17. Attach sealing rings and tighten the nut.
    18. If using 3-probe setup, insert your reference electrode slowly, and make sure the o-ring is flush with the top of the plastic housing.
    19. Wipe off any excess electrolyte that might be on the outside of the cell.
    20. Your cell is now ready for testing.
