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 paper 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.
