Super super slow, filtering time is at least twice as long depending on the type of oil used....


I've seen them but everyone talks about .22 as a standard. So the only real inconvenience would be a longer filter time? Small price to pay IMO. Shit, MCT filters painlessly through a .22 filter. How much slower could it really be? I want to get one and try : )

Same here. Who's selling these filters? I know medlab isn't.
 
Can't remember off the top of my head. They are out there, I've def seen them. I want to say I've seen them as an off brand like celltreat or something.
 
Sterilization and Depyrogenation Tunnel



Yea ok, Bc you quoted a YouTube video....:rolleyes:

Is this a serious post?

Most brewers can't afford a five grand autoclave so you come up with six figures worth of equipment? WTF?
These tunnels are designed for mass production.
They sterilize 50,000+ vials a day, that's more than 1 MILLION vials a month!

Do you already sell that much?
I don't even think
-Naps good ol' days
-Med & lab supplies (empty vials)
-perhaps not even Watson T cyp sells a million vials a month
Autoclaving works wonders for small production volumes


I am finding companies that are local and will sterilize products
via gamma or E Beam. A properly washed and bagged product that gets one of those treatments would be satisfactory, would it not? I'm in the northeast so maybe this isn't a common industry throughout the USA but I am finding this service up here.

The pricing is typically based on cubic footage and I am finding that no minimum size requirements are needed at most facilities.

If one was to brew for more than personal use this may be a good option if quantities are large enough.

But this is all personal speculation based on some internet digging....

Great
But wouldn't be easier and cheaper to buy sterile vials from TOP NOTCH companies?
No homemade Ebay vials

What are you trying to sterilize?
A fuck buddy?
Sorry couldn't resist

Generally, lab glass wear and vials.

I use my oven after a thorough cleaning, but what I am getting at is there are plenty of professional ways to sterilize that don't include alcohol or any other pea brained methods as one member is peddling as of recent.

The only reason I dug as far as I did was to make sure it was a realistic option and had enough of a foundation for me to quote without being horrifically incorrect, I think I'm not anyway.

I realize alcohol is far from ideal.
But let's face it, most UG gear is poured in unsterile vials
so alcohol may provide a partial solution to lazy, ignorant or greedy UG brewers.

One other point I would like to make, everyone is so use to .22 filters, but for almost a year or so there has been .10 filters introduced to the market. IF I were a lab I would be using them as they trap more crap than a .22
The downside is filtering takes longer as the pores are even smaller thus the flow rate is slower.....

I guess MCT will work fine thru 0.1 um
At the end you can only know by trying
I didn't find any online info for that

What do you guys think about these $200 Amazon autoclaves?








They mention surgical equipment so I guess they would be enough for vials
as long as you don't need many of them in a short time

Would rubber stoppers resist autoclaving in these ones?
 
What about these SEOH filters?

Nylon or PES?


They are cheap, but are they good enough?

Jeremy: There's no such a thing like cheap and cheerful; there's cheap and nasty and there's expensive and cheerful.
Jeremy: There's a very good reason why its cheap, it's crap!
Jeremy: "yes but there's lots of things that are cheaper than that. I mean, would you like to have, keyhole surgery on your scrotum? that's very cheap. d'you want that?"

How exactly did this turn into what it has become?

I realize witchdoctor's initial comments were not exactly welcomed, but I, for one, would like to hear some of his opinions as they relate to the hime brewer. Of course taking into account that alot of us took to homebrewing as a cheaper route and to also know what goes into our gear with the exception of not really knowing the purity of the raws we buy from these suppliers.

For me, my process isn't sterile from start to finish, seeing as I don't have a dedicated clean room. I'm of the thinking that you keep it clean as possible up until the point you start the filtering process, and at that point everything needs to be sterile, as has been stated in this thread.

Most of us here aren't mass producing. I make 50ml at a time at this point. My first brew, I made 3 100ml batches and with syringe filters, it sucked.

I'd like us to share methods to keep us safe while also being mindful of budget and stop posting "youtube science."
 
There is bacteria in the air and all around us, most strains are harmless. Even if you super heat the beaker as soon as it cools if it is sitting out for more than a few minutes, airborne bacteria will inevitably land on it. Anyone who has taken a Microbiology class can attest to this.

Sterilizing everything that gear comes in contact with post-filtration is all that should be required.

Disclaimer: I've never homebrewed, but I do know microbiology so take it for what it is.

Did you have a lobotomy performed on you when you were a child? You asked me what pharma companies do not what is cost efficient for a UGL. Jesus Christ, you're so dumb it makes my head hurt.

Prove me wrong then
What is the proper way for big pharma to sterilize vials, you believe?

Please only quote Good Manufacturing Practice processes used by big pharma.
 
Buy vials that are already sterile? One they are very expensive, 2 how would u explain to the end user when they see a needle mark on the rubber stopper? If it were me I would wonder if my mailman drew out all the good stuff and put in useless oil.....

And I disagree with your autoclave comment, many quality labs who want to follow guidelines similar to what a real lab would look like would buy a unit....Its a one time investment, only thing to buy afterwards is distilled water....And yes rubber stoppers can be used in a autoclave.....

That shit wasn't pharma sterile, but it certainly did its job, lol. Why junkies never complain about infections? I used to run heroine through a cigarette filter.
Shit I would have use that needle after u in my day

Can you really do that? Well I guess it's not any better then heating it on a spoon and sucking it up through the fucking que tip cotton.
 
Shit.... i

Was so desperate once while i was on a road trip.... dont smoke and didnt have any q tips so i found a partially smoked cig and used the filter from that.... i could taste the nicotine when i slammed that shit...
You couldn't have used a new one? Wait...this out of a random ash tray?
