Legendary Rotary Evaporator

Hello, i know everyone is quite busy for the exam, 

therefore, 

i plan to update this place much more often so that all of you can actually rest your brain a bit by reading my post

....

OK, maybe not really

anyway, good luck for all of you, hope everyone score HD for everything~!!!

so, as promised, to day i will be explaining the highly sophisticated looking machine 

aka

Rotary Evaporator

so, a rotary evaporator is a device that used to remove solvent from a sample gently and efficiently by applying lower pressure. 

The decrease in pressure also decrease the boiling point of the solvent, which in turn conserve some fragile materials in the extract.

ok, lets start

turn on all this before operation~

and this

Rotary evaporator, an overview

so, it consist of (left to right) an air pump, a condenser, and a water bath.

so, this is the air pump that actually sucks air from the condenser

the tubes~~

condenser

and you will have to fills this tank with water before operation,  this pump was driven by Bernoulli's effect, and the water is used not only to cool down the pump, but also to retain the solvent from escaping into the environment.

now, you connect the tubing to the condenser....

poof, connected~!!!

magically

since it was called an rotary evaporator, this thing is used to control the rotation speed of the  thing shown below.

so the rotation prevent the solvent to become superheated

and also helps to create a thin film of solvent across a large surface

this thing was suppose to be connected to the condenser, but since someone is using,

i could only put it into the water bath.~~~~

so this is the collecting flask, which collects your solvent~~

now the water bath sink~it is suppose to be filled with water during operation

OK

 a valve on the condenser helps to regulate the pressure in the condenser~

some clips to stabilize the collecting flask and heated flask

and the heating element of the water bath~

more information pleases refer to Wikipedia ~

thanks for watching everyone

and if you don't mind

share this post and let more people know whats this

is not really superior to only know this on your own 

waahhaahha

joking~

bye
