Title says it all. I need to incubate at 250 rpm big volumes of bacterial cultures in an orbital shaker that only has "sticky pads". I am using 2L erlenmeyers flasks (regular). What is the maximum volume you would use to be 100% sure it won't fall ?
So far, I have been using 1L (50% of volume) at 175 rpm without problem, but I'm not comfortable cranking the speed up and leaving it overnight.
