FluoroDish Black Wall Cell Culture Dish, Pkg of 100Black Wall FluoroDish cell culture dishes are specifically engineered to enhance fluorescence imaging by reducing optical interference at the source. In fluorescence microscopy, stray excitation light and lateral light scattering can elevate background signal and reduce detection sensitivity. The black wall design absorbs incident and reflected light, limiting off axis illumination and minimizing autofluorescent noise from the dish environment.
