Re: ice trays

From:Lesley Weston

The lab I used to work in was not air-conditioned and it contained a lot of
heat-producing equipment, including the wax ovens. In the Summer, I would
put a chunk of dry ice in a large plastic funnel mounted on a clamp-stand
over the microtome, so that the cold air flowed over the block. It made a
major difference; I was able to cut everything, even during heat-waves.
