sonication with aluminum foil wrapped flask
« on: June 16, 2009, 09:55:52 AM »
I want to extract polyphenols from my tea sample by sonication for 2 hours. As the polyphenols are readily oxidized by light, I have to cover my flasks completely.
If I wrap my flask with aluminum foil completely except from bottom, Will ultrasound energy pass easily through the flask?

yes, but any foil in the water will disintegrate.  one other option is to take an old cardboard box and build yourself a little boxed-in cave.
