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

As in, "Lab" freezers are less likely to *trigger* an explosion, or
are more likely to *survive* or even *contain* one?

In any case, I stand corrected then; some lab freezers may have useful
features domestic ones don't. It would seem though that this feature
is of little relevance to DIYbio, where ether and other highly
volatile explosives are less commonly in use (with the noteworthy
exception of chloroform..).
