Peptide Critic Community

@kRazy-pep No, the batch that failed endo was Tirz, this is Reta.

Nice specific testing. Thanks!

I guess what we don't know with these results is wether the peptide itself survived the 0.1 micron filtration or not.

Btw, I tested the exact same batch, included endotoxins. These came good.

Condensation in the hydrapeak is not the major challenge; condensation in every single vial and inserts is.

Just tested reta I have had stored in the hydrapeaks in the freezer for 8 months. They came 99.9% purity, no trace of endotoxins. Bottom line looks like "don't freak out too much".

Anyways, I'm working on the design of a "Researcher end to end bundle of 3D printable accessories" which have all these nuances in mind.

Thanks. I believe I'm just going to 3d print a few 4-6 vial cases (not insulated like the hydrapeaks) plus some silica baskets and keep my vials in the fridge for the year, vacuum seal the rest with enough silica packets and pop these in the hydrapeaks to freeze.

Been storing stocked up vials in the freezer within the hydrapeaks with the 3d printed inserts, same in the fridge for short term use.

Nice and well organized, however, everytime you need to pull some vials out, the quick shock of room temp makes everything inside the container to condense. I dont think silica gel packets can keep up with that much. Wondering if it is a reliable option at all and probably going to freeze small batches in vacuum sealed bags and bring them to room temp before opening. Not sure for the fridge short term, though.

I do open the hydrapeaks inside the freezer and infrequently but nothing stops the condensation, also, I keep the containers without lid for 30 minutes before closing them.

Is there any good practice playbook to properly handle this popular storage option? Maybe @randy talked about this in the past and I missed it.

Thanks
