Loading, cooling, and package
Touch the droplet with the narrow end of the straw and the capillary effect will force the medium to enter it. Put the straw into liquid nitrogen for vitrification immediately, and then transfer the straw into the pre-cooled container.
Warming and expelling
Tightly cover the wide end of the straw with your index fingers. The medium will flow out from the straw as a result of the increased pressure of warming air inside the straw.
