Question How do I prevent getteing "dust" of Molsieves in the dryed Chemicals?

[Mohammed_Lee]

Like the title says: whenever I store a Liquid over a molecular sieve the Liquid gets light brown fron the sieve. I didn't manage to filter it out with all the types of filters I have at home. Which ones are suited, is there another way?

thx in advance

You rinse them with water before you reactivate them.
Unless you like brown solvent. Don't try to blow the dust
Out, it's bad for your lungs so don't let it get airborne

thx for the Answer. Since I don't own a vacuum stove. can I regenerate them in a regular one? How many °C would you recommend?

 

[Osmosis Vanderwaal]

You can. As high as you can. If you go higher than 450°f your oven will probably smoke you out. 400°f for 4 hours should do it

Thank you!

ok.. so I guess about 2 days with the 220 mine is capable of

 

[Osmosis Vanderwaal]

That's probably Celsius. I'm an American so I think if farenhiet.
220/5=44x9=396+32=428°f

If your 220° is C, that's what I call 428°

 

[Mohammed_Lee]

some sources say up to 400°C, guess that also confused me. I did it now in a DIY vacuum pot, worked fine!

 

[Mohammed_Lee]

Ah, I didn't see the f after the °. Perfect, thx
