Choosing filter papers

[ARMCO]

Thanks Snoman, I will give them all a test.
Thanks Jon, the budget right now is in the air, but things are changing, and more so with my next button. But the $100 is not out of range. The question is I do I buy more material or equipment? Decisions, decisions, :lol:

Shark,
For about double that Sreetips built a great vacuum filtration system. He has a good video. It was clear and simple enough that I was able to duplicate it myself for about =<$200 even here in Alaska. Works AWESOME!

When your budget allows it’s worth it.

I have watched Sreetips video with a lot of interest. I have to admit there were a couple of items that I just didn't catch in his video that I did pick out of yours. I now think I might be able to work with something similar. I will be looking into the needed parts very soon.

Wait til you chew thru your first large lot of high stainless!
It gets real exciting! Some go easy as pie. Others....... Not so much so.

I just bumped into what I think is tin, it sure looks like snot anyway, and started forming crystals as soon as it started to cool. The good side is that I ran these items separately as a test since they were unmarked. (but did test positive for gold)

Well cool. Glad it helped.

Whatman number 1 are a great all rounder. I am not sure what your budget stretches to Shark but I've noticed you're really getting into this so I'll throw an idea out there.

If you get a $100 vacuum pump single stage, and a vacuum regulator then you're set to filter almost anything. You'll know when your settings are too high because you'll blow the filter so practice a lot.

I change the oil in my pumps every day if they have had acidic gases through them and they are still working after nearly 2 years. Oil is cheap.

A final addition would be a flask with sodium Hydroxide in it to pull your air through before hitting your pump. I guess you could also put an inline filter in place however as above I've not needed to do it and the pumps have been running for many hours at a time.

Take what you need from this Shark and discard the rest but I hope some is of use to you.

What does the setup of the sodium hydroxide vacuum flask look like? Do you route the vapors into the crystals or bubble them through a solution?

Bubble it through a dilute solution to neutralize acidic fumes.

Be adviced that the flask train is used in conjunction with a vacuum system and
often as said here in a train of bottles where NaOH is in one.

It is a bubble wash system where the air from your reaction, likely containing corrosive fumes, is bubbled through water with sodium hydroxide in it to neutralize any fumes. Routinely, based on your production, the liquid needs to be changed.

On roughly the same topic, can anyone explain to a non chemist what the difference between qualitative and quantitative filter papers are, and which ones I want to buy for general solution cleaning ?

Better late than never, I just noticed this.

qualitative filter paper is used for general filtration purposes where identifying the presence or absence of a substance is important, while quantitative filter paper is designed for precise measurements and analysis, requiring a very low ash content to accurately weigh the collected residue in a quantitative analysis.
