What is a long stem funnel used for?
Stemmed funnels are used for gravity filtration. They are also used for miscellaneous tasks such as filling round bottom flasks with liquids.
What is a short stem funnel used for?
Long and short stem funnels are ideal for filtering Molded to an accurate 60° angle for ease in fitting filter paper Beaded rim for mechanical strength Long stem, which is constructed of heavy wall tubing Molded to an exact 58° angle , which increases filtering speed High resistance to…
What is the advantage of using a stem less funnel over a long stem funnel while filtering hot solution through fluted filter paper?
Why should you use a stemless funnel for hot gravity filtrations during a recrystallization? Stemless funnels should be used, because with long-stemmed funnels, the crystals come out in the stem as the solution cools, blocking up the funnel. Why is slow cooling important to the purification?
What is the use of funnel in kitchen?
A kitchen utensil that is used to pour liquids and small-grained ingredients from one source into another. Funnels have large open tops that slope down and decrease in size forming a small diameter outlet allowing placement into smaller areas.
What does a funnel symbolize?
The inverted funnel is a symbol of madness. It appears in many Medieval depictions of the mad; for example, in Hieronymus Bosch’s Ship of Fools and Allegory of Gluttony and Lust.
What problem might arise if a long-stemmed funnel was used in the filtration of the hot mixture?
With a long-stem funnel, the air must push up against solvent coming down the thin funnel, which would slow down the filtration process and cause turbulence in the liquid (like when pouring out a bottle turned upside down).
Is it better to use a long-stem or a short stem funnel when doing a hot gravity filtration?
With hot filtration, it is advised to use a short-stemmed funnel (Figure 1.83a) or stemless funnel if available, instead of a long-stemmed funnel (Figure 1.83b), as material is less likely to crystallize in a short or absent stem.
