What's the difference between PES and PVDF for filtration? They both work?

No, Proteins bind to PVDF so you'd lose peptide., PES has very low protein binding properties.

13mm has a holdup volume under .02ml, or 2 units on an insulin syringe vs .08ml for 25mm. 13mm can filter around 10ml, while 25mm is good for up to 100ml.

It is bearable but annoying. Feels like a mild sun burn. My question is, does it run it's course and fade away or is this something I have to live with?

ARA 290, a Nonerythropoietic Peptide Engineered from Erythropoietin, Improves Metabolic Control and Neuropathic Symptoms in Patients with Type 2 Diabetes - Molecular Medicine

Although erythropoietin ameliorates experimental type 2 diabetes with neuropathy, serious side effects limit its potential clinical use. ARA 290, a nonhematopoietic peptide designed from the structure of erythropoietin, interacts selectively with the innate repair receptor that mediates tissue...

Nothing is flagged.
It's just the december classic inspections.
All international lines to USA will have a higher inspections rate, no matter the line.
Trying to get their quotas before the end of the year..

When people are ordering, they shouldn't have to dig through 20 pages of dumb shit.

How fucking entitled are you that you think you shouldn't have to wade through 20 pages of dumb shit.

Now tell me how you feel about almonds?

 

[Savagesteve]

What’s the TA for international? Just noticed the Christmas list has all the shit I need intl instead of domestic lol.

4-6 weeks right now. After the holidays I would say 3-4 weeks.

I think concern may be premature, but Biden did say he intended to implement the tougher de minimus rules before the end of the year. Hopefully this isn't that. Please let us know if you see movement.

Think he remembers saying that? Lol

Makes sense, i always run PVDF for AAS oils.


Do you know if PVDF hydrophobic vs hydrophilic matters for filtering AAS oils. I've seen both kinds.

I was on track for 2-3 week delivery International to USA until this custom's bullshit happened.

Well fuck. That totally ruins my fantasy about the rep typing in thigh highs and a lace bra.

I mean... Being a member since 2016 and still haven't figured out that this forum has a homebrew section.

That does not necessarily ruin your fantasy.

Either will work, but hydrophobic allows for faster filtration.

PTFE or NYLON is best for AAS... PVDF will work but marginal with higher BB content. Best to use ptfe. There is a few charts floating around for membrane compatibility.. somewhere...

Thread 'Filter membrane compatability chart'

I found this very helpful

Take away-

Nylon and PTFE are compatible with ba/bb


Pvdf states "No Compatibility Data Currently Available" for BB
