Mig840 and PES compatibility

[BrunoES]

Hey guys, looking into using Mig840 for my next brew.
Would like to filter it alone before brewing, and am curious as to if it is compatible with PES membranes.
PES is way easier to buy where I am from, and since it's just the oil, and no BB or BA, I would like to know if it's fine.
I am asking because I have seen a lot o posts talking about how Mig840 has solvent-like properties, so I just want to be sure.

If anyone can chime in, I would appreciate it.

Thanks!

Personally I think you’ll be fine bud

Thanks for the input!

Personally, I do too. But would like to get someone who has done it to share their experience, just to be sure.

It is not recommended. I personally use mig840 for almost everything and have done quite a bit of research on this subject.

agreed, just find a proper hydrophobic filter membrane for filtering oils. PES is hydrophilic and meant for water solution filtering

it's "solvent like" properties are nothing more than its hygroscopic nature when compared to non distilled MCT therefore its capable of dissolving a higher % of solute compared to MCT (which also contains higher plant waxes, lipids, water, etc since is not an ultra processed fraction of plant derived oils).

Look, water is a solvent, anything can be a "solvent". A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. MCT, GSO, motor oil, saliva, etc are all "solvents"

Thanks for the reply! And for all the info! So even if it's only the oil by itself, without any BB or BA, it's a bad idea? And if it is, how bad are we talking about? I am asking because I can find PES directly from legit lab supply stores where I live, and any other membrane material I would need to import from somewhere else, like Aliexpress, which isn't as safe I suppose.

the short answer is it seems to be resistant, where itll suffer is flow rate. id make sure not to add the BA until post filtering since PES seems not resistant or Limited resistance to BA

Thank you! Appreciate the time you took to clarify everything. I am planning on filtering just the oil. I can take the low flow rate. I can find the syringe PTFE ones, but I assume it would be too slow to do it without the vacuum system. Do you know if people ever use the syringe ones (PTFE) for amounts like 400ml?

The volume they can handle is on the specifications. Mostly can not do more than 100ml. Mines clog after 50 and becomes very hard to press.

Oh, I was more asking how fast is the filtering with syringe PTFE filters. I can get like 100x in a box, but I assume it would take several hours to go through 400ml+, the speed of the syringe filters is what I would worry about

when it becomes hard to press just use a new one. It can break up if you straft pushing harder and harder. They costs next to nothing.
If you are brewing a large volume your are better oof with bottle top filter
