The ibidi product family is comprised of a variety of µ-Slides and µ-Dishes, which have all been designed for high-end microscopic analysis of fixed or living cells. The high optical quality of the polymer material is similar to that of glass. This allows the researcher to perform a wide variety of fluorescence experiments with uncompromised resolution and choice of wavelength. The Grid–500 is a grid structure for relocating events. It provides 400 distinguishable observation squares of 500 µm edge length. The grid is clearly visible by phase contrast microscopy and based on the high quality ibidi Standard Bottom. Ø 35 mm, low wall (800 μl volume), grid repeat distance 500 μm, #1.5 polymer coverslip, tissue culture treated, sterilized, 60 pcs./box
