This "device" seems like a major waste of money.  We air dry gels all the
time, using a piece of plastic about 2cm bigger on all sides than the gel. 
Sandwich the wet gel between two wet sheets of cellophane (ours is from
Biolabs, in their gel-drying section of the catalog; I'd be interested if
folks know of a cheaper source) then smooth the sandwich on the plastic
piece, and use binder clips all around to hold the cellophane taut.  Put a
fan on the sandwich if you're in a hurry; a 1mm gel will dry in an hour or

By the way, we first thought that we could use the glass gel plates for
this; it worked once, then the second time the sandwich stuck to the glass
and cracked.  There is no problem with the plastic sheet.

good luck
