Hi Paul, I did so many of those PMMA blocks cracking. Take a under pad, line your blocks not too many and cover with another under pad and start (literally) hammering them one by one with hammer gently I am not kidding. Make sure you wear safety glasses and double gloves to protect your hands. When the blocks are cracked remove them and rinse with tap water and small glass pieces will go into sharp container. I know seems very complicated but it is not. If you have more questions regarding this please fell free to contact me. Good Luck Shakun

I always use plastic vials. Obviously the vials have to be broken to get the blocks out. Does anyone have some advice on the best way to do this? The guy who brought them said he thought I could "use liquid nitrogen", but had no specifics. Any help will be appreciated. _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
