Hello,
I am pretty serious about getting a vacuum pump with the following specs:
36 LPM (240V, 50 HZ)
2 STAGE
50 MICRONS VACUUM
2800 RPM
0.15 Litres oil capacity
6.5 kg
This particular one is a tool, used by tradesmen in car air industry. This is the cheapest pump i can find in Australia, which goes into micron vacuum scale.
Quickly checking the available pressure calculators:
50 microns = 0.05 Torr = ~ 0.07mbar
Would i be correct in thinking that this is considered fairly "deep vacuum" and is suitable for laboratory work such as vacuum distillations of ketones.
I also checked the nomograph, and according to my calculations, this pump will boil water at just below 0 degrees Celcius - does this sound right?
Thank you,
Sponsan.
