| Petri dishes for tissue culture, including a serrated ring to safely grip the dish, and an exclusive double marking area which acts as a bottom/ top dish positioning aid. Only the perfectly flat surface of the bottom dish is treated for cell growth. The 6 stops built in the dish lid guarantee an efficient lid fitting and an optimal gas exchange during incubation. A numeric scale 12, 3, 6, 9 has been set on the periphery to ease locatinq. A discontinued stacking ring reduces condensation in between stacked dishes and thus eliminates adherence of the stacked dishes. Sterilized by gamma radiation. |  |
