This may be of help.. decanting can be very messy specially if youre messing with solvents containing your spice and highly caustic basic liquid below it. Better pipette or turkey baster the solvent off.

i like to use a thick glass long neck wine bottle for extractions, and fill it up to the neck with basified solution, so that the naptha sits up top on the long slim neck portion. Makes recovery very easy with a glass baster and the last few ML of solvent can be grabbed with a glass eye dropper. Works great! i have a 400ml, 750ml, 1500ml, and 3000ml to make any size extraction a breeze.

for lime tek like q21q21's tek 2 french press works well as one can use it to squeeze the remaining naphtha out.

I found a separatory funnel on a stand with a steel support ring very easy to use. When the two layers seperate, I just drained out the slurry through the stop cock in the bottom into the mason jar he mixed in and through the top he poured off the naptha (in his case) into another small container for precipitation. So many different ways to choose right?

I like to cool in a beaker/jar, pour out as much as I can without losing solid, warm to room temperature to redissolve, and then evaporate the remains on a butter dish.

glass eye droppers work great for getting the last few ML of solvent. any basic slurry will be at the bottom allowing you to squeeze out the slurry without losing a drop of solvent. they can be found at a pharmacy like CVS/rite aid, $3 for a pair, one straight and one angled tip. i love using these for the last little bit of solvent floating on top.

glass eye droppers work great for getting the last few ML of solvent. tilt your vessel, and pull the last bit of solvent with the glass eye dropper, then any basic slurry will be at the bottom allowing you to squeeze out the slurry without losing a drop of solvent. they can be found at a pharmacy like CVS/rite aid, $3 for a pair, one straight and one angled tip.

Glass eye droppers all the way. I use a extra long one for 4oz amber bottles, with a bit of electrical tape wrapped around the bottom of a 3ml luer lock oral syringe to form a seal between them. Use the luer lock to get suction, but don't let the solvent go above the top of the glass, plastic and np's no beuno.

Works good to get more solvent in each pull, when eye dropper tops usually don't displace enough volume to use the glass tube to its full capacity, 3cc's of air is more than enough to pull solvent to the top of the tube when using a 3ml luerlock and 4oz bottle dropper tube.

Just be sure to get a good tight seal with the tape, and don't let the solvent ever come in contact with the luer lock or the electrical tape.

For larger volumes, glass/stainless steel turkey baster followed with a sep funnel decanting to drain away any water that got sucked up. But using limo for my basic soup pulls, you really only need a small amount and most of the time, glass droppers do the job fine.

I have those exact same droppers. A little short, though, which makes them hard to use for getting liquids out of erlenmeyers and tall, narrow jars (although I suppose decanting out of an erlenmeyer doesn't really make a whole lot of sense).

 

[Electric Kool-Aid]

I too use the small droppers for all of my pulls. (10 pulls on my last batch! Ok ok, I like to get ALLLLL the last tasty bits out of the mix, call me crazy! )
The small droppers are totaly the way to go! You can take like 5 minutes to pull, no big deal. At least you can see what you are pulling and it draws great on the side of that glass by the curve of the surface tension. You can get just about every last drop of solvent out! Its like the hidden secret!

I use glass syringes. Much less hassle than the medicine droppers IMO. I think a sep funnel is even better, but I don't want to keep too much obvious lab stuff in the house.

 

[Drew7]

I don't like using separatory funnels for decanting. Once all the liquid is gone, getting the solid out of the funnel is a bit of a challenge.

For lime tech you could first pour off the naptha into a glass pyrex measuring cup (the one with the handle and pour depression). This would not need to be exact if a re-x is going to be done. Then pour this into the precipitation tray. If any material gets into the measuring cup it usually won't flow out into the precipitation tray.

Re-x should be performed to get any additional junk that comes over to the precipitation tray.
