Cant get solution to filter. MCT oil / Vac pump

[superbane]

I assume you sterilize one or two at a time as needed for each brew, how many ML are you able to get out of each filter?

Well you can sterilize as many that will fit into the autoclave without overloading it.

I’ve done 300ml and haven’t had flow rates reduce.

Usually the manufacturer has flow / filter rates and the pertinent information documented somewhere

Awesome, looks like this is the way to go. I really wish more people ran this set up, for a minimal about of time invested yous getting a much better set up, and cheaper to run.

Yea I'm looking into this also.
I'm at where I might just buy a glass setup instead of the plastic bottle tops. I figure I'll be using it for some time to justify the cost to myself.

I used the caulking gun and syringe filter and imo it was a bitch. To filter 100ml took about an hour of squeezing the fuck outta that thing. I just think that time is better spent and with less effort and over the long haul it's worth it.

I’m posting this because a few of you may have perspective on the issue and I would like to solve the problem as quickly as possible lol

The following is from a conversation I’ve been having with daylight driller.

I guess I should state this before I go further. I have a Buchner setup. Anyways here goes:


I feel dumb as hell sending this message but I’m in a jam and really do need help.

I got 200ml of tren/test/mast I need to filter.
It’s 5% overdosed. 75mg each compound per ml. MCT oil. (This has held steady and is fine)

I have a 2.5 can vac pump
I used ptfe support screen gaskets to shim up the stainless steel support screen.

I have tried both 0.22 and 0.1 millipore pvdf filters. (I got the .22 after the suggestion of DD because filtering through the 0.1 was hours for 10ml)

I just tried to filter with the 0.22 and it literally would not filter warm oil. The oil just sat on top of the filter. It saturated but it would not filter through.

I thought perhaps I had ruined the filter in the autoclave so I tried a fresh one that wasn’t autoclaved and yielded the same results.

The vac pump was maxed out and started collapsing the hose. (Hose 5/16” ID x 7/16” OD - 50psi)

If I lifted the filter off of the stainless steel support ever so slightly I would get vacuum. So the filter was acting like a stopper.
Not even drops.

Pvdf filters.
Millipore gvwp 04700 - .22
Durapore vvlp04700 - .1

I’m at a dead end and do not know what to do? Clearly I am overlooking something.

Stay away from Buchners
oil can leak around the membrane unfiltered without you even noticing it (yes, even with the support mesh.

Stick to self contained units.

You should try Mig 840. Filters fast, you could filter 100ml in 10-15 minutes

you can finds some north amerian sources for the set up on the bays. Even if you buy the $150 set up with $2 filters, 10 brews cost you $170. if you buy individual bottle top filters at 15USD that's $150 so after 12 brews you break even. The bottle filters can come sterile so you don't have to autoclave them. but if you use the media bottle to avoid plastic breaking you needs autoclaves. either way if you clave anything the glasses one makes more sense and pays for itself, if you get the China ones it pays after few brews.

I did the maths and sourced for weeks, for few hundred dollars you can have build filtered clean room, cleaner than any lab I've seen here. Is a dentist office really clean? stuff still floats around, seal it off and medical grade air filter isn't expensive.

I run two different Buchners. I don’t have this issue nor did I have this issue in high school. You’re a narcissist aren’t you?
