Vacuum filtration is used instead of gravity filtration in order to achieve a dryer product in less time. The faster process of vacuum filtration allows the slurry to remain cold and in cases such as with benzoic acid more crytals will remain formed at colder temperatures. Gravity filtration is most useful when the solid is to be discarded and the filtrate (the liquid that flows through the filter paper) kept. Vacuum filtration is often faster than gravity filtration and is most useful if the solid must be kept or if a filtration must be done rapidly. A vacuum from an aspirator or a vacuum pump is used to pull the liquid through a funnel containing a piece of filter paper, while the solid is left on the paper.

What is difference between micro filtration and hepa filtration?
HEPA is stands for High eff ency particulate filters & its normally stops particles size more than 0.3micron & using for clean rooms . Micro filtration have higher filtration level with respect to HEPA around 5 micron .All filters are using on demand on area filtration level
What are some facts about gravity?
Gravity is a force on earth that pull everything down. On the moon there is less gravity than on the earth
How do planes defy gravity?
They don't defy gravity. Gravitational attraction affects planes just like anything else. The wings of an aircraft generate lift which when the plane is going fast enough is a stronger force than the gravitational attraction of the earth. To do this the wings split the air flow going over it into an upper and lower part. Because the wing is curved it forces the air to travel further when it flows over the wing than when it flows under. The molecules of the air in the upper part are therefore slightly separated out from each other which creates a small vacuum effect. The wing rises to fill this vacuum pulling the aircraft up with it.
Which warms up faster sand or water?
sand heats faster because it absorbs heat faster than water!!!!!!
How can you use the word faster in a sentence for smaller kids?
The girl ran faster than the boy.
Why you use gravity filtration than evaporation to get calcium carbonate?
why was gravity filtration use instead of evaporation
Does the Hollywood Twilight Zone Tower of Terror drop you faster than gravity?
yes, it drops you about 5 times faster than gravity.
Does gravity travel faster than light?
No.
Light travels faster in glass than it does in a vacuum.?
No
Does a light travels faster in glass than it does in a vacuum?
No
How much faster will a bullet fly in a vacuum than in atmosphere?
In a vacuum a projectile will maintain its launch speed (muzzle velocity) until gravity pulls it to earth or it strikes something in its path. In absence of gravity it will maintain straight-line flight and velocity until it strikes something. Atmosphere creates drag which slows bullets dramatically.
Is vacuum has a zero gravity?
Not necessarily. A vacuum is merely any volume having a density lower than an arbitrary amount.
What is the speed of gravity?
C To expound, gravity and light travel at the same speed. * It is a fundamental fact of nature that nothing can travel faster than light, but matter slows light while gravity is not slowed or screened by anything. So light and gravity only travel at the same speed in the vacuum of space away from any mass.
Can anything travel faster than the speed of light through a vacuum?
No.
How fast vacuum tube works?
it is faster than air as a medium
What is faster than a bullet?
* The speed of light in a vacuum, * The speed of sound,
In a vacuum the speed of ultraviolet radiation is faster than the speed of light?
no
