Miking up your PMMA mixtures

From:Gayle Callis <uvsgc@msu.oscs.montana.edu> (by way of histonet)

It is not that difficult to make up your own PMMA mixtures, did that
exclusively, mainly due to the cost of kits, and could vary what I needed
for the hardness of bone, implant, microtoming or grinding.  Many people do
this as they use such huge volumes of reagent unless you have unlimited
funds for kits.

It is no less toxic to work with separate reagents than with a kit.  There
are MMA mixtures that do not require any washing of hydroquinone
(polymerization inhibitor) out of monomer, getting rid of a messy
additional step.  A GOOD fume hood is a necessity EVEN with kits.
