Hoefer GD2000 - Manual (Page 16)

4. Operating instructions
After you have attached the vacuum pump
to the GD2000, follow these instructions to
prepare the dryer and gel drying stack. Once you
set the temperature and the timer, the GD2000
automatically starts the vacuum pump and turns
on the heat after 10 seconds. At the end of a
timed run, the heat is turned off first and the
vacuum ten minutes later.
Step 1: Prepare the dryer
Wipe away all contaminants with a soft damp
cloth. See “Care and maintenance” on page 17
for recommendations on how to remove accu-
mulations of radioactive materials. Fit the stain-
less steel screen into the recess on the platen and
then place a sheet of filter paper on the screen
slightly larger than the surface area required by
the gel(s). The paper should not extend over the
ridge that surrounds the platen.
