Reading the several millions of posts on flat bottom flasks is swim to understand flat bottom flasks are unsafe under vacuum situations?
Swim was planing to make the mock up Perkin receiver on rhodiums page:

But replacing the vertical vacuum receiver and rbf with a filter flask? so as in the pic but the ground glass joint from the bottom of the dropping funnel is hooked up to the filter flask and the sidearm vacuum connection is hooked up to the hose. ::)
it would work but would there be a problem with the flat bottom vacuum flask under a high vacuum such as vacuum distillation rather than the low vacuum of vacuum filtration...?
