Brew Particulates?

Hey, Meso

I have an interesting situation. After brewing with sterile vials, ba, bb, and mct from medlab as well as Tisch .22um PTFE Sterile filters I have particulates that I can see when using a backlight on the vial and turning it.

I have re-filtered into new sterile vials and the same particulates remain. I then filled a vial with unfiltered MCT to see if it could be the filters. The same particulates are present.

Since I already tried new vials, I'll be trying out new filters later but the question is why would the unfiltered MCT and the Filtered brew have the same particulates if it was the filter shedding? (Maybe the filter isn't doing its job at all and the particulates from the MCT are passing straight through?)

If anyone has any insight into this, I would really really appreciate the help. I'm at my wits end. Video attached below. Ignore the dust on the outside of the vial, the particulates swirling in the oil are the concern. I have let the vials sit still as well - these don't seem to be air bubbles.

Anyone? @narta do you have any idea what those small particles I'm seeing are? I bought a different brand PVDF hydrophobic filter to try instead of the PTFE hydrophobic Tisch filters I was using to see if it helps and will report back once I get to re-filter.
 
Have you gone through your whole process with a different clear liquid, like water or alcohol? It's only a troubleshooting step, but it may point you in a direction. Stoppers can also be dirty, so rinsing with alcohol may help.

I re-filtered into a completely different brand of sterile vials and the same particulates remained. The filter should remove any particles that can be seen by eye though right? If they can remove microscopic bacteria, I don't think I should be seeing anything.

sounds like your filters are bunk? ? Possibly got a "bad batch" ?

The vials were labeled sterile. Were they clean?

They sell ultra-spec vials that are clean and sterile. Adhere to USP 788.

These steril vials are USP 788 Particulate Standard compliant.

Yes a functional 0.2 um filter will remove visible particulates from your unfinished oil product.

That's why I suggested you try with a different fluid. You're trying to isolate the problem to a specific component. You can try with a different fluid right now, as opposed to waiting for new filters, new stoppers, or new vials to come in the mail.

First you change the fluid. If you can get particle-free water or alcohol, you know it's something to do with what you're putting through the process.

If you swap the vials, and there are no particulates, you know it's the vials. Same with stoppers, filters, and everything else. Just repeat until you've found the cause.
 
The vials I used are ultra spec from medlab.10ml.

I'm a bit more confused now... I put distilled water unfiltered into my amazon vial and my SPEC Vials from medlabsupply. Both show the same "dust" particulates.

I doubt both the SPEC Vials and Amazon sterile vials have dust inside? The SPEC vials are supposed to be compliant with particulate regulations.
 
I have put benzyl benzoate, distilled water, and regular mct into these sterile spec vials from med lab, and vials from amazon.

So different vials, 3 different liquids and I didn't even filter them, and somehow I am ending up with particulates in all of them. I'm at a loss.

What would your next troubleshooting steps be? @psauce

I tried isolating the liquids, no luck. I tried isolating the vials by using amazon and med lab - no luck. This time I didn't even filter the liquids, yet they have similar particulates to my filtered brew.
 
I had a friend at one time that had this issue the problem was he drew gear with the filter then injected the gear into a vial with the filter on thus reintroducing the contaminate back into the gear it was filtered out of. It was funny I feel like it would of been a funny reel to watch on YouTube.

What kind of syringe are you using?

Have been major recalls of Made in China syringes over the last couple of years.

I used a 50ML Nipro Syringe for filtering with an 18g nipro needle and a 23g to vent.

When performing my other tests with the Amazon/medlab vials, I used a 3cc exel syringe.

I have now put unfiltered BB, unfiltered Distilled Water, and unfiltered MCT into both KS-tek Amazon vials and Med Lab Spec vials - All 6 vials have some particulate in it. The ones with water the particles seem to fall to the bottom easier because its less viscous.

I don't think most users get right up on the vial with a flashlight and nearly blind themselves to get the perfect angle etc like I did.

What are the odds that both med lab spec vials and KS-Tek amazon have dust in them? Probably pretty slim... so I am mind blown as to how all vials with different liquids have a dust like substance - especially since they werent filtered this time.

Are these yours?

Honestly, I'm at a loss. Only thing in common here are the vials right?

I wonder if it's glass delaminate, That's actually a big problem with borosilicate glass,
