You didn't understand my message my friend I said His link was expensive 85 euro for 100pcs.How is 40 cents per filter expensive? I want to see this much cheaper alternative!

Those are expensive you can find a lot better prices same quality
On AliExpress or here as well
Sterile 0.2 μm PES Syringe Filters
Hydrophilic PES syringe filters with single or double-layer membrane. Pore sizes of 0.2μm. Diameter of 13mm/25mm/33mm with Luer lock. Sterile individually packed.shop.cobetter.com
Just don't get the one with the .65 prefilter. We don't need it for our purposes, and it will cost you some peptide.

Buy a caulk gun. Your hand will thank you.

How can you tell you've blown a syringe filter? Does the back pressure just suddenly let up, or does the case break before the filter does (I hope)?

The pressure in the plunger drops significantly. Caulking guns suck honestly. The weighted jigs that keep a constant pressure on the plunger are the way to go some people have made some out of wood and posted pictures on meso. The beauty of those is you can set it and forget it and walk away the caulking guns need constant babysitting
In my experience the syringe break before the filter and even if it doesn't blow and you blow the filter it goes from: this is fucking. Slow to... Ups it's flowing like water.
But I have to say after having tried the caulk gun I believe 10ml/5ml syringe could be faster. I have to retest it back to back but last time I was filtering 20/30ml of carrier oil with a 5ml syringe and it was quick as fuck.

I had a 3ml syringe that wasn't moving, then suddenly "gave"after pressing hard enough (still some pressure). Just wondering how I would know for sure I broke the filer, as there wasn't any other sign. With PES, if there's an air bubble, it apparently takes a lot to push it through so I assumed it was that,

The blowouts on those typically happen around the edge almost impossible to see. Something that may help and we use it on filtering cannabinoids in an ethanol solution is to pull a vacuum on the receiving flask and have head pressure on the feedstock. Did you pull a vacuum on the receiving vile? That can usually help as well. At least to get it started It's better to do that than to simply throw a needle in the receiving vial to aspirate to atmosphere
Should be super easy to filter with 3ml syringe. Like 20/30 seconds max. Strange

from my experience, it usually breaks at the luer lock joint where filter attaches to syringe, i just snapped one yesterday refiltering some q oil , it was at the end of the filtering process so i didn't make a mess , i usually filter 40 ml per syringe filter as to not overload the filter

Anyone get primo 100 in the promo? I emailed the rep and I am waiting for a reply. According to the skus the red tops are the primo but I noticed a couple of vials crashed which makes me think it may be the cyp and the primo 100 may be the green tops. I think the grey tops are the sustanon.

i use a 20 ml syringe and it seems to work pretty darn good ,

It usually is. Only "stopped" completely a couple of times, which is why I think it was a bubble.

Well these are tiny amounts, 1-3ml of reconstituted peptide, and the pressures I'm talking about were no where near breaking point of the 3ml syringe, just suddenly impossible to push without a "shove". I just don't know how "fragile" the syringe filters are. With breaking luer lock joins and exploding syringes, I assume much tougher than I imagine.

My bad I thought we were talking oils here I've never filtered small amounts of peptides lol
Orrrr u got some dirt in dem derre pep o tides…. Ch y na dirt….
So is it customary for tracy and another rep to both just stop responding to emails? Especially when u ask them questions and then request an item??
Seems like ive never made it thru an entire order due to them always either stopping comms or just never answering the questions i have..

A lot tougher they resist a savage like any of us pushing with a caulking gun man.. trust me you will never break it by hand

For sure. you could filter 10ml of many though a tiny 13mm syringe filter and probably more.
But some "dirty" peptides fully clog them at less than .5ml, and even a 25mm filter (5x the filter area, should be good for 100ml +) starts to get gummed up after just 3ml.
It's always the peptides with the worst site reactions that clog the filters fastest. I don't think that's a coincidence.
PS: (not a comment about QSCs peptide quality, this is observed with certain pharma peptides as well, hence the "bedside filtration" used by some hospitals, and increasingly required by some pharma companies in their reconstitution instructions)
PPS: (so please no "special gift" in my order)
