@Ghoul I was gonna ask if nylon would qork for peptide fiktering cause I messed up and bought 100 of them to fing out they were 13mm.. but i remeber reading that nylon od protein binding so probly no huh

Sorry man, nylon is what's used when you *want* to capture protein. It's very high binding.

That'd what I figures.. i haven't filtered my peptides before but I do the 3ml carts so I may start doing it just for shits and giggle..

 

[Ghoul]

Thanks i see now.. thats not a bad deal either. @Ghoul you say these are superior.. in tour opinion??

Pall Supor PES are the best for peptide filtration, but they don't seem to offer sterile PTFE that would be used for gear. Maybe someone could figure out which Pall filter membrane would be appropriate for oils. I just use the cobetter PTFE.

Dirt,
Are you saying ALL the Biomed are "bad?"

I picked up the same exact 10 pack from Amazon as well, havn't needed them yet, but I can still return them.

No because I have use plenty of them before and they worked just fine so I don't know if it have a bad batch or what so I juat recommend the other brands people and myself are talking about that have never had problems with

Well a couple post up they posted a link where there was a prfe option that was sterile.. i just couldn't locate it on my own.. i like how they offer the 33 diameter version as well.. and they are no more expensive that the other brands.. im going to five them a try

Those suck bro! Ive popped them numerous times making a mess. Get the pekybio ones mentioned here or get celltreat on ebay.

Good to know, I'll check those out. I ordered those from Amz, but haven't used them yet, and won't after the feedback, thanks. Heated gear and 3ml syringe worked fine with Whatman filters in the past.

 

[Humble-Beast]

didn't someone just say that they used that brand of syringe filters and it turned there product "cloudy"? Sometimes its better to use tried and true products instead of trying to find the cheapest deal,,,, And reinvent the wheel,,,

I didn't see the post, but yeah. I've used Whatman in the past no problems, then saw this deal, but haven't used them yet. I won't now, thanks.

That mother fucker will do that... this last hour has been the best interaction I've had here in a little while... everybodys been cool and respectful.. i have enjoyed the shit out of it

Dude its nice when its calm and not a tren raged interaction! @Ghoul please stop making us buy more crazy shit! But real talk you always know about the good shit! Just when I think Im getting something good you always have something wayyyy better! You definitely know your shit and respect! I have those stoppers for you my brother!

Ill be honest they are better than whatmans! The construction on the celltreat and peky are much better in my opinion and have yet to pop any!

Odd. My SSA package has also been sitting in LA since 12/19 and it also moved towards my direction just now. Maybe you are next

Me too

West coast too? Any east coast movement? Customs detention doesn’t sound too good.
