You can probably avoid all that and filter with 10ml syringe by hand
Totally agree.
Just sharing options for those who are planning to start filtering.
I used 30ml to filter my UGL oils while waiting for my raws to arrive and get tested. Planning to stick to smaller brews in future so a 3ml syringe is probably sufficient without any gun.
Not sure this has been shared but I found this informal study comparing 13mm and 4mm PES filters that suggests a volumetric loss of 28.5iu and 5-7iu respectively.

Great price on those filters, good find.
"Air purge" always bothered me because the foaming effect creates the air/water interface we know facilitates aggregate creation, so better to use a low hold up volume filter like this, or, flush the filter with an amount of BAC equivalent or greater than the holdup volume through the filter to get the rest out.
And of course, a greater volume of BAC used to reconstitute, like 2 or 3 ml cuts down the loss to half or a third as well.

Not really unfortunately.
Even if one or two tested sterile, that's no guarantee, unlike an FDA regulated source.
That said, radiation sterilization is practically free for the manufacturer, so if they're individually packaging them it's likely they're not faking the sterilization.
On the other side of this, of the peptide samples tested by Jano, 20%+ fail sterility tests. Even commercially produced peptides by lab suppliers in the US are recommended to be sterile filtered before use in any application that matters, like experiments on living organisms some.
So these filters are unlikely to make things worse than not filtering at all, like most.

I don't think that applies to oils

No it doesn't. The report was related to peptides, and I wouldn't use anything smaller than 25mm for oils, the loss isn't significant for those.
I don't know if this is mere pedantry but would a higher or lower gauge needle be better for reducing loss/waste?
Perplexity says higher gauge retains less fluid, which makes intuitive sense. However, chatGPT says lower gauge = faster flow = less retention, and that higher gauge leads to 'capillary action' inside the needle?

It's really not gonna be a lot of volume either way. You can also dilute it more so whatever is left has less active ingredient.
