I also use lot of agar every day. As agar-agar (crude form) in
petri-dishes, for growing bacteria etc. And in it's purified form as
agarose, mainly used to separate (based on length) of DNA (and RNA)
fragments. Funny that you can use it as a size, but does one need to
harden it? I assume so. I guess you also have to protect it from the
little critters who like to dine on it.
