vacuum distillation pump
Help for a newb!
Ive done some oil distillation under a vacuum pump. I normally used the faucet at full with cold water for the condenser. As a newb i though a vacuum
pump was better then an simple aspirator, so i bought a SCHUCO aspirator pump. It says its an oil-less pump and it hast an antibacterial host to
prevent contamination with a canister, (that i did not use).Now this oil burn over 200*C, when i set up for vacuum distillation i did not set a trap,
manometer and neither a filter. I know this is a medical vacuum and i though it would work so i simply conected the vacuum host to the adapter. This
oil burned under 100*C, however i think it worked, i am not even sure it did or done the right way.
Questions
Is this vacuum suitable for vacuum distillation? ( with the kit, gauge, hydrophobic host and canister)
IF YES- Do i still need to set up a trap and/or filter?

You should probably use a trap.
A medical vacuum pump may not generate
A high vacuum. Many of those only generate
A few psi. Also the diaphram may not
be suitable for exposure to oils.

Aspirator pumps generally have a water bath. pump, a pair of aspirators
The pic looks like a cheap diaphragm pump
a good aspirator pump will provide between 5 - 10 torr
