lwr you need a tight seal.. trust swim on that.
LWR is ez too but the longer time means the smallest leak will leak the most..
One of the great advantages of the long wet reflux, aside from avoiding the creation of unwanted by products during the hot fast start, is that the reflux can be done without any pressure at all, will a condenser with an open top. Once the HI is made and largely absorbed by the water put in the reaction to absorb it all, the balloon that is useful during the early HI production stage can be removed and the reflux done without containment.
The problem I had with push pull units and hot fast cooks was that when you had a seal leak you lost too much of the HI and had inconsistent completion ratios. A leaky seal can ruin a hot dry reaction quickly. What do you think is escapting from the seals, anyway? HI is, since you don't have enough water to hold it, it escapes, and once its gone, its gone.
This is not a problem with a LWR.

This is simply not true. Nothing is returning to the reaction vessel that is of any use to the reaction itself.. The tanks are not even necessary, They control smell and enable recovery of I2. Thats about it. The pull is nothing but the lack of energy and has no mystical part in the production of meth. By time the pull is noted the reduction is already over..
A leak will expose you to HI gas which is not good, It will result in stains on the walls and everything else the gas contacts and that ain't good. One big thing is you wont get to see the dramatic pull when the second phase is wrapping up depending on the size and location of the leak and for the new bees that ain't cool at all, So leaks are defiantly not wanted. As far as hampering the reduction of E to meth, a leak just ain't going to do that.
And as for the question of how the push pull works, that was meant in reference to the on goings inside the flask itself and not to how the tanks work... The starting ratios in mass are about the same except for the amount of H2O peasant.
3I:3E:1RP is the magic molar ratio, no?"
Would that be the same as 1:1:.3?
Is that a molar ratio or a mass ratio?
This might sound stupid but here it goes anyway.
How can a molar ratio be expressed without water being figured in as well?, I understand % of a solution and its molarity some what. I'm not to good with moles so bare with me.
In a LWR the molarity of the HI is always changing being H2O is produced in the reaction itself. In this light it still 1:1 molar but broke down at 57% and involving many hours at reflux to reduce correct?
A "push pull" has lower amounts of
H2O there fore the concentration of HI is way Higher than that of a reflux resulting in a shorter time for reduction but the 1:1 ratio is the same as a reflux.
Comparing one to the other and you will find a major difference in molarity so why isn't H2O figured into the molar ratio when it is expressed?
I am a little confused here. I know this has been covered but WTF, help me out here...
Oh yeah, one more thing on the push pull sense I'm here and don't want to look like a complete dumb ass thats been kicked by a gang of moles.
There is hardly any pressure in a push pull set up right.. The only pressure will be determined by the weight of water that hast to be pushed from the first tank and this is short lived once its in the second tank the pressure is off. A proper set up and one should be able to blow into the hose and just with the air in your lungs push one tank into the other then your just blowing bubbles at this point with very little effort..
Sense there is a hose exiting the second bottle that is open to the atmosphere the system is not a gas trap. It a gas scrubbing tank, water being the scrubber and the gas being the scrub bee. The gas escapes the tanks cleaner than it was with less of an oder leaving a valuable precursor behind for a later recovery..
It's the same as if a single hose was run from the reaction vessel to an outside vent. There are many bees that have done exactly this.
This bee has always done the push/pull minus the tanks. He found that their only advantage was to control the smell. Swim recalls on Worlock's old site he recommended running 15 ft. of hose out the window if cook under an Oz. of E. This bee always did like to put a loop or two in the hose just to watch when suckback occured.
Jacked is right bout(or anything pertaining to the pp) a small leak not affecting the outcome, this happened to swim's buddy just last week when to cork wouldn't seal off for a few minutes. Swim told his buddy the dope probably wouldn't bee worth a shit. He was wrong, the gear was just like the other two hundred rxn's before, quality meth.
