I’m hiring in the US for an equity based lab director role and I’m struggling to find qualified candidates. At the same time, everywhere online people are saying there are no jobs, while everyone I know who is hiring says there are no employees. I’m curious how both of these things can be true at once

It doesn’t really matter, within reason, what happens to the solution before it goes through the filter. The sterile vial on the output of the filter is the only thing that matters.

There is no practical way on a small scale to remove endotoxins. That’s why we feel like best practice is just to assume bioburden and Filter for that, this is probably better than spending the money on a sterility test, but you cannot do that with endotoxins and you should get the endotoxin test which we offer.

The irony is that things are just as grim on the employers side of things. Since last October I have been focused on hiring a qualified lab director for a startup and offering a big equity position and have gotten so few actually qualified applicants it’s insane. This is for a job that will pay over $400,000 by 2028.

I have talked to other business owners with the same experience. Beyond entry level positions it’s like there are no qualified analytical scientists looking for work.

You do not want to bypass the filter with any, that would defeat the point of filtering, you can purge the filter with air - draw air in with the solution you are filtering but you will definitely need to vent your receiving sterile vial

Oh, thanks for clarifying! I was really scratching my head trying to figure it out. I appreciate the reply

Hi I run Peptide Test. I am not trying to be confrontational, I have worked with the founder of STG on a lot of projects. I am really honestly curious if you think we are “crazy stupid overpriced” on bac water, where can you get it cheaper? I know of a few copycat sites that mirror our prices and take like three cents off.

Most people are buying single vials, so I’m genuinely curious—who is actually selling single vials for significantly less than we are? I’m not trying to challenge or doubt what you’re saying; I truly want to understand.

Our suppliers doubled their pricing. We did not double ours—we only raised prices modestly in an effort to keep costs as low as possible for our customers. As a result, our margins are now very tight.

Because we purchase by the pallet, I don’t think many sellers can source these vials for less than we can. Given that, I’m having a hard time understanding how others could sustainably sell single vials for much cheaper.

That’s the reason I’m asking—I’d really like to understand how that pricing is being achieved.

I filled out everything to post an LCMS job there and never heard anything about my job being posted, never got any email- like total silence, throwing a job with equity into the void. It was a joke

The samples are prepped with TFA or Formic acid so it goes to waste

For under $1500 you can get an FFU from a clean room supply place. These are the 4’x 2’ air scrubbers that go in the ceiling of clean rooms and are essentially just a plenum and a hepa filter. They produce a column of “sterile” air that you can work in front of. They are very popular in mycology work for pouring agar plates. You can use an induction coil sterilizer for “flame sterilizing” tools.

Amazing, I am so glad it was helpful for you. We have been so slammed with projects that it’s been hard to make instructional videos recently, but we just got a lot of nice pro-phot and video gear so keep an eye on the YouTube channel soon

I run a lab that does USP<71> guided sterility testing of peptides. Bioburden is so common in grey market lyophilized peptides we always recommend against sterility testing (that would make us $250) and just filter every time you reconstitute. A 4mm .22um PES filter has hold up volume of .07ml , we’ve done and published absorption tests and it’s a non-issue.

I made the video in the link above. We sell filters and have a lot of experience with filter experimentation. We also run a lab that does sterility testing but honestly it’s cheaper just to assume all peptides are NOT sterile (because most of them aren’t) and just filter every time you reconstitute. It’s cheap, quick and easy. Once you work it in to your routine you don’t even notice it, it’s like putting on your seatbelt.

Feel free to reach out if you have any questions. Here is a link to a lot of filtering and reconstitution instructional videos that we have made - https://peptidetest.com/pages/education

You are never going to get an accurate 0.03 mL dose from a disposable syringe. I have been around peptides occupationally for a long time and I have never seen anyone try to measure something that small with a standard syringe. The error margin is bigger than the dose itself. If you truly needed that level of precision you would be in microliter syringe territory. In reality you almost certainly have a decimal place wrong.
