This question is part of the following Ask The Expert session:
One observation that comes up in looking at tissue culture flasks is that not all flasks are designed equally. Flask bottoms that connect to the neck via a slanted slope actually is a non-treated area where cells do no grow, but media covers regardless. So one train of thought is to utilize a flask in culture in which the entire bottom is treated for cell culture, thus maximizing cell growth area and minimizing media wastage. Open for discussion on your thoughts or suggestions.
