I used to be extracting with ultrasound baths either ethanol, methanol or hexane as. Solvent
It does help in the extraction speed but you loose that time in cleaning up for it pulls more nasty s
Overall not some tech to discard
Yust haven t found the time yet to finetune still many questions on it s use
A strong ultrasonic field will disrupt cell walls and let the chlorophyll out.
Not a good idea for the same reason that chopping biomass is inferior to shredding it by hand.
A weak field like in an ultrasonic bath should improve mass transfer and reduce extraction times.
If you get something expensive where you can precisely control the power then you can find the right spot. Get the stuff you want and not the stuff you don’t. Otherwise you just have to guess and you are definitely down in the bath cleaning sonication range, but getting the ratio of volume to power just right would be a game.
