Filter paper has a rough and smooth side. Does it matter the orientation?

I like Experimenting with small amount of chemicals, I'm a big fan of Micro-chemistry & Electrochemistry everything can be packed away easy !

Does it matter what filter paper you use can you like coffe filter paper?

Very informative!

Pls add video regarding lipid extraction

Very helpful, thank you!

Hi! I'm doing a project on granolas for one of my courses and one of the things that we're trying to evaluate is its peroxide value. In order to do so, we plan to do a lipid extraction. During our preliminary testing, we used petroleum ether as our solvent in the extraction and noticed that it took an extremely long time to evaporate (we ended up letting it sit overnight and came back to the lab the next day). I was wondering if you would know why this is happening - if another solvent would be the solution? Why is our solvent taking that long to evaporate? From research, my group members and I found that petroleum ether would work as well. Thanks!

Fact: you searched for it

I think limonene, being a hydrocarbon, could help with alcoholism, which is dangerous because of the horrendous withdrawal symptoms. I think maybe limonene could alleviate the symptoms long enough for a recovery to take place... in terms of chemical dependency. Psychological addiction is altogether a different beast.

this is kinda satisfying

This is so poggers. where is the onlyfans!!

very nice
