Peristaltic pump setup?

[T-Bagger]

Anyone have experience and a setup pic of a peristaltic pump with capsule filter?

Never used one personally @T-Bagger but I know its a rotating circle that squeezes the fluid from bottom to top in a pulsing flow its used in heart surgeries an extremely contamination sensitive scenarios because the fluid has no contact with the environment at all there is no air forcing it or a vacum pulling it its just a rotating gear that squeezes the outside of the tube an that pushes the fluid through the tube into the filter I feel that it is kind of extreme for homebrewing but shit you can never be to sanitary

Prestine/ Trenity in the underground uses them and crosses teen or something into Deca or some switch because they filter multiple compounds with it. I don’t see the point unless you’re filter liters and liters of fluids as that’s what they are designed for and why they cost so much.

From what you know is it better to just use a standard pump setup like in the others have used?

Deff better to use other filter pump setup unless you decide your going to start doing a couple gallons at a time lol there expensive I dont know how much pressure they produce but the filters for them tend to be very high volume filters an not needed imo a vacum pump or hand pump with a bottle top or zapcap will suit your needs a lot better most likely

Syringe -> bottle top -> membrane -> Polly cap/ millicap.

Let’s call bottletop and membrane the same. Caps are great for filtering huge amount and are quiet. But you have hoses you have to buy or sterilize every time on the output side. Filters are expensive for home brew unless you filter everything for years at once for the personal size.

Bottle top/membrane can be used in much smaller batches size and the reason I went with membrane was it’s $100 for vacuums set up and filters are 1/10 of a bottle top. Yes I have to sterile the flasks and stuff but when I’m saving 90% on filters it’s great plus if you filter in to glass media bottle with bottle top you still have to steriles the bottle.

If I'm doin a 100ml or less I do syringe filter into 1 or 2 50 ml vials with a caulk gun an mct oil its fast anymore than that I will use the zapcap or bottle top filter

100ml just seems like a waste of time for some reason. I’m so used to doing 500-1000ml batches. Do you back fills the syringe or change out needles to suck up from beaker?

Much appreciated bro

I always back fill it an I usually stick to 100 to 150 ml batches I will do about 5 or 6 compounds in 100 or 150 ml batches I never brew everything at once in case something goes wrong

I’ve worked in places where things are cooked by the gallon so I’m still adjusting to talk in mL

Any idea how this would be setup (peristaltic)?

Any way you wants really. How much are you trying to filter makes the difference. There is no vacuum or priming needed so in simple terms you could stick one tubes into the beaker for oil run it to the filter and the output goes to a sterilized media bottle where you then put into vials. I assume you’re filtering 500ml to 1L+ otherwise is kind of not useful. But take a media bottle with a stepa rubber covering a cut a slit into it. Then screw the septa cap on after its sterilized. Shove the steril output tube into it and it keeps everything more clean instead of tube into open bottle. For storage replace cut cap with whole one.

Alsos, you could sit there and fill up the open vials directly if you wanted to sit there moving the tube around.

Also pump is before filter so oil -> tube -> pump -> filter -> Sterile tube -> sterile container. Remember with the pump the tube runs throughs the pump in one piece so you only have single piece of tube before filter and sterile one after filter.

Thanks a ton for the knowledge brother!

So with a peristaltic setup what filter would be good to use. I know the whatman poly caps are common. But have you used or know of anyone using different types? I’ve been reading about millipore millipak and millipore steripak. They seem to be cheaper and have a minimum volume of 10-20l.

I’ve heard of capsule filters being used.

@master.on has talked about them several times. He might have a picture or an idea of how it works.

That would be awesome @master.on

Haha, no sourcing for me brother
