A filter funnel is a funnel shaped filter that is used to separate solids from liquids. By passing the mixture of solid and liquid parts through a filter, which is either a piece of filter paper or a glass frit, the solids remain in the filter funnel and the liquid is passed into a collection flask below. A Buchner funnel is typical kind of filter funnel.
See the Web Links to the left for more information about filter funnels.
A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, much spillage would occur.

∙ 12y agoA Büchner flask, also known as a vacuum flask,[1] filter flask, side-arm flask or Kitasato flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck. The short tube and hose barb effectively acts as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator, vacuum pump, or house vacuum. Preferably this is done through a trap (see below), which is designed to prevent the sucking back of water from the aspirator into the Büchner flask.
The thick wall of the Büchner flask provides it the strength to withstand the pressure difference while holding a vacuum inside. It is primarily used together with a Büchner funnel fitted through a drilled rubber bung or an elastomer adapter (a Büchner ring) at the neck on top of the flask for filtration of samples. The Büchner funnel holds the sample isolated from the suction by a layer of filter paper. During filtration, the filtrate enters and is held by the flask while the residue remains on the filter paper in the funnel.
The Büchner flask can also be used as a vacuum trap in a vacuum line to ensure that no fluids are carried over from the aspirator or vacuum pump (or other vacuum source) to the evacuated apparatus or vice versa.

∙ 9y agoThe Buchner flask is also called a vacuum flask. It has very thick sides so that it can withstand holding a vacuum inside and is primarily used in conjunction with a Buchner funnel to filter samples.

Does oil pour faster than water?
No, oil does not pour faster than water
Why do aluminum foil melt butter faster than a spoon?
aluminum foil melt butter faster than a spoon because aluminum foil collects heat faster than a spoon
Why does Co2 diffuse faster?
why does Co2 diffuse faster than So2
Why does diffusion happen faster in warmer substances than in cooler ones?
Molecules move faster when warn than when cool.
Is a lambergini faster then a baugatti?
Yes a lambergini is better and faster than a bagutti!
Why does salt dissolve faster than in ordinary water?
because it is salty
Which travels faster airwatersoundor light?
Light. No ordinary matter can travel at or faster than the speed of light.
Why is broadband faster than an ordinary internet connection?
because the signal is the broad
Why hot water freeze faster than ordinary temperature water?
This is a pervasive misunderstanding. It, in fact, does not freeze faster. Since the water is initially "hot", compared to "ordinary" water, the rate of temperature change is faster as it approches freezing (basic thermodynamics), however, hot water has a bigger range to travel than ordinary water
Do granulated solids flow faster or slower than powdered solids through a funnel?
the granulated solids travel slower than powdered due to granulated have grains and it take time for it to travel through a funnel and it could get clumped up at the bottom of the funnel .As powdered it passes through not clumps
Why is it faster for water to fill up without funnel?
A few reasons: 1. The spout acts as a throttle on the flow of water...it narrows and restricts the stream. 2. The flow through the funnel is due more to gravity, than to the velocity of the water flowing into the funnel from a hose ....hard to speed up the flow. 3. Turbulence or water circulation inside the funnel will slow and affect the vertical descent of the water through the funnel.
Is a tornado worse than a hurricane?
The winds in a tornado funnel are perhaps faster (and therefore more destructive) than a hurricane, but the diameter of a tornado is very very small compared with a hurricane.
Is a car with a turbo considered a performance car?
Most of them probably are. Like the porshe cayenne turbo is faster than the ordinary cayenne
What did the technology do to improved ordinary plastics?
The technology have made them reusable. They are producing plastics in such a way that they can be decomposed faster than the ordinary plastics. They provide longer use and are produced in a very easy and in the modern style.
What's better long term: Laser or Ink-jet printers?
Laser printers are much more better than the ordinary ink jet printers for sure as they are faster and more durable than the ordinary ink jet printer ounces

This is a "court stenographer." They use special keyboards which allow them to type must faster than an ordinary keyboard.
How long does it take for a snail to travel 1 foot?
it depends on the snail and its experience. if it is a racing snail, he'll be faster than an ordinary snail.
