Yes, I switched to making my own glass milk. Works great with DNA >500 bp
from TAE gels. I bought 2 kg of glass powder from a local pottery outfit,
probably enough for 500ml of glass milk.
I don't have the method on this machine but I'll try and post it in the 
next few days.
You can make a lot of friends supplying your dept.
