What kinda setup are you referring here?
Share some pictures.

I am considering these two. Before ordering, I want to know if these filters can be reused by simply replacing the membrane? Or do I need to buy a new unit after every 500 ml?

These are one time use(and dispose). Membrane cannot be changed. You'll need glass filtration apparatus to change membrane but it has to be handled very carefully to ensure sterility. And, as it is glass it breaks, I've broken a few recently.

thanks for the answer! could you recommend where you bought this glass filter from? unless you get banned for it, of course?)

I'm from SE Asia and I got from a local vendor.

Here you go. Just message him and ask for the 90mm filter funnel instead of the 70mm as the 90ml filters more and is a more common size.

Thanks a lot for your help friend. You have greatly accelerated my search, maybe you know where you can buy filters 0.22 and 0.45 nylon or PTFE specifically for this filtration system? I am sincerely grateful to this forum and all its participants for their disinterested help and all kinds of assistance!

Yes but you do not want nylon it would take you 45 minutes to filter 100ml. You want PTFE. PM me I'll send you a link to the filters.

@Heavy Iron thanks for sharing this. I‘ve never homebrewed but want the cleanest and most efficient setup once I do. This definitely seems the way to go! Saved for future reference.

Sorry for the stupid question, is it possible to change the membrane in the vacuum filter after running 500 ml? And is it possible to change the membrane 0.45 to 0.22 in one filter?

No stupid questions when it comes to sterility, sanitization, and harm reduction my friend! I saw your question has been answered already. I usually buy a case of 12 of bottletop filters (disposable). So you could always run it through a .45 filter then just dump it back into a
.2 but I would suggest using separate media bottles. So that way one media bottle is catching.45 filtered liquid and the other is catching a refined .22 filter.

No do not buy that you can go on alibaba to boading pump.com or CRpump.com, and buy one 5 times as good for the same price. Your welcome for the connections. Email then and tell them to message you on Whatsapp so you can get them down on the price. Keep in mind they can always drop the price. $400 shipping included is a good deal.

Thanks for the tips!!

Thank you for the photo this is helpful for a newbie like me. Is there a reason you chose this pump vs a different type ?

Cleaning the glass media bottles isn’t that difficult. First I wash the lids with dawn, rinse with hot tap water, then rinse with distilled water and then rinse with 70% alcohol. Then I wrap them in a sheet of foil and bake them at the recommended temp for an hour.

Now I start on the bottles. I use Dawn detergent, a bottle brush and hot tap water first. I wash and rinse well with the hot water twice. Then i have two squirt bottles that I fill one with distilled water and the other with 70% alcohol.
View attachment 100629

After rinsing well with the hot tap water, I hold the bottle upside down and squirt the distilled water up at the bottom of the jar and allow all distilled water to flow back down the sides and out of the open top. Then with the bottle still upside down, I squirt alcohol at the bottom of the jar and allow it to run down the sides and out of the open top. I also squirt the outside down with the distilled water and alcohol. Now I lay the bottle on its side till I have all of them clean so that minimal particles in the air can settle into the bottles. Then I stand them upright and loosely place a sheet of foil over the top of the bottles and bake at 450 for 1 1/2 hours.

Edit: After removing media bottles from oven, I cover with the lids that have already been cleaned and baked and they will remain sterile until ready to use the next time.

I have a question: isn't heating the glassware at 170°C (340°F) for 60 minutes, 160°C (320°F) for 120 minutes, or 150°C (300°F) for 150 minutes enough to kill germs?

I don't think any surface organisms will survive past that temperature. And, if so, why use the alcohol?

This is a legit question. Not trying to antagonize you.

I use the alcohol purely to keep my glassware clean. By rinsing with the alcohol, remnants of water are removed off of the glassware and it dries without any hard water stains. If the glassware is placed in the oven before all alcohol is evaporated, it needs to be heated at a lower temp till all alcohol is evaporated. I use 200 degrees. If not the alcohol will evaporate but leave some brown stains on your glassware

TL;DR - I write too much shit.

There are two different kinds of pumps being show - vaccum pumps, which pull air to suck the oil though the filter, and peristaltic (pressure) pumps that push the oil directly through the filter.

Vacuum filtration is usually cheaper and easier for people that do low volume filtration. The 500ml filters are usually under $20/ea, and good for like 50 vials or so (realistically, unless you filter in several stages, you'r probably going to get super sloooooooooooooow flow after the first 250ml or so). Getting something with a replaceable membrane makes it even cheaper. The vacuum pump is maybe $200, and you can use the same pump for other things, like, say, charging the refrigerant in your car. The biggest hurdle is finding vacuum line, since most air lines are intended for pressure and not vacuum, and will collapse under a hard vacuum. Practically speaking, you're looking at 30-60 minutes to do 500ml of oil if you aren't filtering it in several stages.

Peristaltic (pressure-driven) pumps and filtreation are fast. You can push a few liters through a capsule filter in under an hour. (They can also be messy as shit, and cost you 250ml of finished test if you don't use clamps to hold your PTFE hose onto the barb fittings of your filter.) Capsule filters are more expensive than filter membranes, or even disposable bottle top filters, and peristaltic pumps that will put out enough pressure to do anything can also be quite pricey. You'll need to get the appropriate size of PTFE tubing to run through the pump, since different pumps will use different size of tube, and figuring out which tubing you need can be a pain in the ass.. But did I mention how fast they were? If you're doing serious volume, then that's 100% the way to go.

In my opinion, most people that are home brewing are best off with vacuum filtration. Even if you're also brewing for your buddies, you'll be able to do sufficient volume without a problem.

I agree with some of this but I disagree with some other points made.


There is no reason you can't filter at least 1,000 ml if not 15 to 1700 ml through a 90 mm PTFE filter membrane using vacuum filtration if you know what you're doing.

No if you're making more than that let's say $5,000 mL of each compound yes you're going to want to use a peristaltic Pump and a capsule filter.

However I disagree with you losing 250 ml that's only if someone is stupid enough not to use a fucking hose clamp when they clamp the hose to the filter and if they do clamp it to the filter they're only going to lose the holdup inside the capsule filter if they don't know how to suck it through using vacuum but even then they're only losing about 30 to 50 ml if you're making 5,000 cares about 30 to 50ml.

As far as the pump being pricey my vacuum pump cost $250. Now granted it has a gauge that you can adjust the pressure and all that but my peristaltic pump only cost me $450 and it is actually a dispensing pump. Meaning not only can you filter with it but you could also program it to fill whatever size file with whatever time or pause time in between each vial. For instance you can program it to dispense 10 mL every 3 seconds that way you have three seconds to move the old vial out of the way and the new one underneath.

Now obviously if you buy a top name brand one from here in the US yes you're going to spend $1,000 or more but you can get just as good of one from across the pond which I think I posted a link for above from companies such as CR pump or Boading pump. I will post another link here Below in case there's any confusion.
