Hi Hadley, We get our blades from EMS (Electron Microscopy Sciences): http://www.emsdiasum.com/microscopy/products/preparation/blades.aspx?mm=10#71990
On this page you'll find the injector blades. Further down they have the double edge blade you can break in half and use in the holder. Try those and see if they work for you. Best wishes, Teri Johnson, HT(ASCP)QIHC Managing Director, Histology Facility Stowers Institute for Medical Research Kansas City, MO _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
