* The unique recessed lid on this dish offers excellent stacking stability and space-saving.
* It works with most models of media pouring equipment; an absolute must for manual pourers.
* Four ventilation lugs on underside of lid allow for venting and prevent condensation from developing and dripping onto the culture.
* The extremely flat bottom allows a reduction in the amount of media required.
* Patented cross ribs on the bottom make the dish resilient and resistant to warpage when the media is poured at a high temperature.
