Thanks. Thats a great solution. Unfortunately these filters are quite expensive for one time use. Is it possible to use fritted glass filter filters instead? If i understand correctly they can be cleaned and re-sterilized.

What vacuum presure it is? I can’t get fluid flowing at such rate, using quick filtration filter, and fluid only flowing dropnby drop.

@sciencewaikato5734 2 жыл бұрын

It really depends on the solid that you're trying to filter, if it's fine particular matter it is difficult to filter as it will clog the pores quickly.

why is the vaccuum pipe attached to the top of the container not the bottom does it make a difference?

@sciencewaikato5734 2 жыл бұрын

You need to attach the hose to the nozzle on the vacuum flask, and that is at the top. That allows for the filtered liquid to collect in the flask without being sucked into the vacuum hose.

I kind of want to buy one of these setups just to make coffee. I feel like you could get some really smooth coffee by vacuum filtering it from the grounds.

@slowedits2063 2 жыл бұрын

We were talking about vacuum filtration in my chemistry lab and the lightbulb immediately clicked.. I’ve been manually filtering my cold brew at least 2 times or else it’s not smooth. But it takes a looooong time if enough sediment is floating in the coffee. Strongly considering getting a setup

@redtsun67 2 жыл бұрын

@@slowedits2063 I wonder if the process would be quicker if you passed the hot coffee through a conical sieve to remove the larger bits of ground before filtering it.

@roboslug7582 11 ай бұрын

If you bind the tannins and other impurities with some sort of sticky protein, like casein, ahead of time, you can actually end up with crystal-clear, pale yellow coffee. It has a distinctly coffee flavor, but much more subtle, and with very little bitterness. It's pretty crazy! And it allows you to put coffee flavor in things that you normally wouldn't because of the color, like pancake batter or donut glaze, or even things like chicken soup, which might sound odd at first, but a splash of clarified coffee actually makes chicken stock taste extra "roasty", which is delicious.
