which method is better(reflux or push/pull tank)?

[omid_safari]

are they different in amount of pe/i/rp materials?
swim always use a plastic ballon in ice water as reflux.
but clean up inner lyer of ballon is impossile and he use new ballon on next reaction and he must cut all hoses.
he think push/pull method is easier way but swim think about that in the push pull tank HI dissolve in water of tank and reduce yield of meth!

A long wet reflux would be more forgiving to the unexperienced Swiy. Push pull would be faster but is more demanding of pure reactants and requires extra equipment. Both methods should essentially have equivalent yields given the same reactants used.

Also plastic should not be used for the balloon, Swiy would want to get a "punch balloon" for refluxing.
