Silicone staining pad
Made from white silicone, a non-reactive material. Pad has 40 cells in 5 rows of 8 each. Each cell is half-sphere shaped with an opening of 6 mm dia. and 5 mm deep. A few drops of staining solution is added to the wells and grids are then immersed and retrieved as per staining procedure. A watch-glass plate comes with each dish to reduce oxygen and evaporation.
