==== Before starting ====

  * Fill a liquid nitrogen transfer dewars. Make sure it dry before beginning
  * Assemble the necessary tools:
       * Flat-T autoloader forceps
       * C-clip holder wands (one per grid)
       * Rings and C-clips (one per grid)
       * Screwdriver
       * all part of the transfer station for grid clipping:
               * Table-top cryo dewar (and cover)
               * Aluminum & brass specimen transfer pedestal
               * circular platform aimed holding wands
 




====Load C-clips into the holder wands.====

    * 1. Use forceps and firm pressure to insert a single C-clip into the wand.
              * Make sure that the C-clip is hugging the inside wall of the wand.
              * Use forceps to adjust if necessary.
    * 2. To align the C-clip at the tip of the wand.
         * a. ++Hold the wand vertically by positionning it into the circular opening of the brass part of the transfer base.|<div>

         * b. Press down on the wand trigger to engage and align the C-clip at the tip of the wand.
    * 3. Inspect proper placement of the C-clip

=====Prepare the transfer station setup======

    Arrange the transfer setup as pictured. It should include the specimen transfer pedestal, loaded C-clip wands, and autoloader forceps.
    Additionally, place clip rings (flat-side down) in each of the four mounting positions in the brass portion of the transfer pedestal.
    Inspect each clip ring to make sure that the clip side is face-up.
    Once clip rings are in place, rotate the brass disc such that all clips are covered. This will ensure they do not move while cooling the station.
    Place cryo-EM grid box(es) on the sample pedestal. Open them using the grid box fastener wand. Keep the grid box top attached to the fastner wand until needed.
