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.

Similar to Chien Staining pad, but slits are in mesa shaped platforms. Stains hold on top of mesas and are more stable if pad is moved. White.
Unique silicone rubber pads which act as effective resting points for electron microscopy grids, during processing. Bumping, jostling, jerky movements and carrying accidents can destroy or damage valuable EM grids with mounted sections. Grid Holder Pads minimize such damage by the unique "clean" adherence of the grid to the silicone rubber surface. Three types listed. White.
25 numbered squares, 1-25. 70 x 70mm. Fits square Petri Dish.
16 numbered squares, 1-16. Fits standard round Petri Dish. 70mm diameter.
16 numbered squares, 1-16. With finger tab for easy removal. 80mm diameter for standard Petri Dishes.
The staining pad is 3.5" diameter (8.9cm) and fits inside a large glass petri dish; when this dish is covered with parafilm evaporation is limited.
The pad was designed to save chemicals when processing small specimens. Can be used in the Microwave Processor, resists most chemicals and is easy to clean. Angle cut on one corner for orientation. 40 concave recesses, 4.5mm dia. x 1.5mm deep (0.18 x 0.06").
The overall size of the pad is 41.91 x 69.85 x 6.35mm thick. Shown actual size.
