Title: Vacuum Destilator
Post by: Gringo on September 25, 2003, 05:57:00 PM

Hi Everybody!

I am glad this page exists, even if it is often hard for me to understand everything...

Every time I read in a post vacuum destilator I thought that THIS has to bee the mightiest thing on earth!!
I read it so often, you could use it in such many diffrent ways, that I cannot imagine, what it exactly does...
I even dont know how it looks like!

I checked severel pages. But damn! They ARE expensive!
Cause of that problem, i dont know if they are the right ones...

Title: Rotary Evaporator?
Post by: Rhodium on September 27, 2003, 01:21:00 AM

Perhaps you are thinking about a

Rotary Evaporator (https://www.thevespiary.org/rhodium/Rhodium/pdf/rotary.evaporator.pdf)

(https://www.thevespiary.org/rhodium/Rhodium/pdf/rotary.evaporator.pdf) when saying that they are very expensive? This kind of equipment is lab luxury, but for the hobbyist, you can almost always substitute it with an ordinary distillation setup with magnetic stirring and a vacuum source (a cheap aspirator, or a vacuum pump).

Title: Distillation For Dummies
Post by: Rhodium on September 29, 2003, 06:31:00 PM

It seems like you need to read the following:

Distillation For Dummies (https://www.thevespiary.org/rhodium/Rhodium/chemistry/equipment/distillation4dummies.html)

(https://www.thevespiary.org/rhodium/Rhodium/chemistry/equipment/distillation4dummies.html)

(and yes, you put the teflon-coated bar magnet inside the distillation flask, in the liquid to be distilled. How else would it be able to stir the liquid?)
