Re: [DIYbio] What freezer for a starting DIYBio lab?

Kitchen freezer without auto-defrosting would be perfect, although
Mega's advice is good: stuff the freezer with "thermal mass"
(ice-cooler-packs) so its temperature stays fairly constant despite
opening/closing/powercuts/defrosting-cycles-you-didn't-want.

"Industrial" equipment and "lab" equipment is sometimes valuable, and
sometimes just a ripoff designed to scare beaurocrats who don't
understand what they're paying for; when asked to buy a freezer for a
lab by a PI, a bureaucrat is going to assume that a "lab" freezer has
some magic special sauce a normal freezer doesn't. I have yet to learn
of a magic freezer.
