[Histonet] Removing PMMA blocks from glass vials

[Jack Ratliff]

You need to first make sure you are using polypropylene vials.....the  
polyethylene vials will melt when using MMA. Next, use a box knife to  
score the sides and pop out the block. Larger plastic molds can be re- 
used if you tap out the block by beating it on a counter top.
