The Chien Staining Pad is also ideal for staining grids in the microwave processor. The silicone pad is flexed and tabbed electron microscopy grids are inserted into the slits. When the pad is unflexed (laid flat) the grids stand vertically, allowing the surface tension of a droplet of stain to cover both sides of grid. Blue or white.
FLEXING THIS SPECIAL COMPOSITION MOLD WILL NOT RESULT IN GRIDS FALLING OUT.
