Brew Particulates?

[V.primal]

Yep, I just got my ALK vials in and put hospira BAC water in it straight. Has the same dust look I'm referring to.

At this point, i've tried 3 different vial brands recently and looked at 5 different vial types - all sterile overall. All had what I am referring to.

I've tried 3 different filters with no different result. I've tried BAC water with no filter either.

So, at this point I have nothing left to test and will assume its normal since all gear I've looked at has this. The only way to see it in any vial is to clean the outside very well, put directly ontop of a flashlight, and look with a jewelers loop or magnification while attempting to not burn your cornea out. LMAO

Any chance what you are looking at are tiny air bubbles?

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.

You have to flush the filter with like 5ml of plain warm oil and bb first to remove any potential filter fibres.

Also be careful not to mistake air bubbles for particles.

I was about to post that they look kinda like tiny bubbles until I saw your post.

I still did though.
