This is something that sort of frustrates me during an extraction, it feels like I always have the wrong size of containers / glassware for the volume of liquid I end up with.
For simplicity lets think of STB extractions though it should still follow for the volumes during A/B extractions once the Naphtha is in, my thinking is that if using something like an Erlenmeyer flask which tapers up at the top leaving a narrower but deeper volume up towards the neck which is ideally suited to pipetting off the Solvent.
I've tried a few things, Swing-top Kilner Jars, Erlenmeyer flasks, big Pickled Egg Jars etc. I end up feeling like I've always got the wrong size.
As a totally fake example, something like:
50g Plant material = 0.5L Flask
100g Plant material = 0.5L Kilner Jar
200g Plant material = 1L Flask
250g Plant Material = Pickled Egg Jar etc etc etc
*These are completely made up btw*
I've just watched through a YT vid I had bookmarked, so the following works for a 1 Litre Erlenmeyer flask so wonder if this could be a baseline that could be doubled or halved:
750ml Distilled water
100g Caustic dissolved in the 750ml water
100g MHRB mixed into the Caustic water solution
*multiple thorough mixes*
150ml Naphtha
Total= Approx. 1 Litre, maybe a little more, in a 1 Litre Erlenmeyer flask
My current on-going 125g extraction only ended up with a very shallow layer of Naphtha on top of the MHRB soup in a Pickled Egg Jar (2.27 L) which was going to cause problems when I come to pipette off so I've split it between 2x 1L Erlenmeyer flasks.
Which would be best, add a little more water to each flask / add a little salt-saturated water to each / or simply add more Naphtha?? (I'll be Freeze Precip so used Naphtha will be recovered)
But yeah, its tempting to order a 500ml and a 2L Flask for future extractions
