Most researchers we deal with already know headache of sourcing a clean solvent base for fragile peptides—what they need is something that won't break down a reconstituted protein before they even get it in the freezer. This comes sterile-filtered, non-pyrogenic, and holds at >99.9% purity with that 0.9% benzyl alcohol as built-in preservative.
It practically lives at room temperture, about 20-25°C, as long as you keep vials out of direct light. We've seen some labs try to save it for reheating later, but honestly it's not meant for anything beyond a single puncture, or maybe two if you're careful—benzyl alcohol keeps bacteria down, but needles pick up junk faster than most realize.
CAS 7732-18-5 isn't something you'll see listed label, but basically it’s just distilled water with enough benzyl alcohol to stop microbial creep. The liquid itself is crystal clear, no floaters, no fog—actually looks exactly like you'd expect a pharma-grade solution to look. A 30ml vial usually lasts a few sessions or so for most reconstitution work.
You'll get it in either 10ml or 30ml glass vials with a standdard rubber stopper—pretty easy to draw with a 1ml insulin syringe if that's your setup. We usually have stock, but confirm lead time if you need more than 50 units, because bulk sometimes runs a day or two behind.
Now about applicaion—this is strictly for peptide reconstitution and related in vitro research, semaglutide reconstitution included if that's your drug of choice. It's not fit for injectable use or any human biowork, no exceptions, and the grade is fine for lab-level reproducibility but not for anything clinical or living systems. Most buyers go with the 30ml vial for repeat steps.
Yes, the 0.9% Benzyl Alcohol acts as a preservative, allowing the vial to remain sterile for up to 28 days after first puncture when stored properly at room temperature and away from light.
Absolutely, we can supply a COA with each batch that verifies the >99.9% purity, sterility, and non-pyrogenic status. Just request it with your order.
We have a MOQ of 10 units per size, so you can order 10 of the 30ml vials or mix with 10ml vials as long as the total hits 10.
Shipping to the UK typically takes 5-10 business days via tracked courier. We handle all export documentation, but you're responsible for any import duties or customs clearance on your end.
We currently only offer the 10ml and 30ml glass vials for this product. Custom sizes would require a larger MOQ, so feel free to reach out if you need something specific down the line.
