MightyVac metallic hand pump kits is what you want ! the only one that reaches really 29 psi and keeps them for more then 10 mn + with a vacuum chamber that can cop with < to 8 -10 g. of errls!
@smokum, 12 vac for that load is a little overdo IMO...at some point you are just oxydizing your oil with more and more tiny oxygene bubbles, right? I always stop at 5 for average 3gr of final product !
EDIT: read me right, not saying you did anything wrong or that lowered the quality of your product, just trying to determine where is the limit between efficiency/productivity and the added quality value it brings to the final product! My self, by security, used to do sometimes 8 or 9 vacs but the experience has shown me the product doesn't change that much after the 5th vac...so maybe you can save some time/energy in the process, that's all! Cheers!
