Re-circulating vacuum pump oil in a Deep Well Jet piped to

a Convertible Jet Pump should make a fairly decent way of

getting millitorr vacuum pressures.

I did this with a Jacuzzi pump and a scrap deep well jet

using water for getting 20 torr vacuum.

 

Especially if you get it cheap on eBay.  :-)
