HOMEMADE PLUNGER
Vitrification instrument: EMBL design
A small vial of ethane is placed inside a larger
liquid nitrogen reservoir. The grid holding 3
microliters of the sample is held in place at the bottom
of a plunger by the means of fine tweezers. When the
liquid ethane is ready, a piece of filter paper is
then pressed against the sample to blot off excess buffer,
sufficient to leave a thin layer on the grid. The filter
is removed, and the plunger is allowed to drop into
the liquid ethane. Once the grid enters the liquid
ethane, the sample is rapidly frozen, and the grid
is transferred under liquid nitrogen to a
storage box immersed in liquid nitrogen for later
use in the microscope.
