The footprint of the tray is compatible with standard ANSI microplate holders. There are two water troughs on either end of the tray and two slots for XonaChips™ (XC150, XC450, XC900, XC-T-500, or XC-T-1000). Silicone devices mounted on glass or any other slide based microfluidic devices that you want to use, are also compatible with these trays. Within each slot there is a cut-out to improve image quality using inverted microscopes. The ChipTrays are tissue culture ready.
