What really matters here is the concentration accuracy—1000mcg per 2mL vial is pretty much standard for most metabolic or neurological studies, and we've had researchers tell us it saves them time not having to dilute or re-measure. The clear red solution is good visual check, too, since any discoloration usually means it's been mishandled.
Purity runs at 99% by HPLC, which is better than some bulk reagent-grade stuff you'll see floating around, and it's cGMP compliant so you're not guessing about production conditions. Storage is straightforward—2-8°C for short-term use (usually a month or so) and -20°C if you're stockpiling for a longer project, and stability holds for 24 months form manufacture if you keep it cold.
We've had a few buyers try using this for cell culture work, but honestly it's better suited for in vivo or ex vivo metabolic studies—the preservative system (benzyl alcohol, 0.9%) can mess with sensitive cell lines if you're not careful. Most labs that order it are doing neurological function assays or B12 deficiency models, and they typically go with the 10-vial box as a starting point.
Each box comes with 10 vials, and our company can do custom concentrations or packaing if your protocol calls for something different—just give us a heads-up on lead time, which is usually 2-3 weeks for non-standdard stuff. The MOQ is one box for research quantities, so you're not forced to overcommit.
Anyway, teh key thing is that it's a ready-to-use solution, so no reconstitution headaches, and the COA is included with every batch—we've had auditors flag that as a plus. One thing I'd mention is that the vial rubber stoppers are butyl, not latex, which matters if your lab has allergy protocols.
We usually have stock on the standard 1000mcg/2mL concentration, but for any customiaztion—like 500mcg/mL or different box sizes—confirm lead time before ordering. Roughly 80% of our orders are for this exact strength, so it's a safe bet for most research setups.
Our MOQ is 1 box, which contains 10 vials. That's for research quantities, so you can start small and scale up as needed.
Yes, we offer customization on both concentration and packaging. Just let us know your requirements and we'll work out the details.
Typical lead time is 2-3 weeks for standard bulk orders, but it can vary based on the customization level. We'll confirm it once we have your specs.
Absolutely, we supply a Certificate of Analysis (CoA) for every batch, confirming the 99% purity and cGMP compliance. Just request it with your order.
For short-term use, store at 2-8°C. For long-term storage, keep them at -20°C. Properly stored, they stay stable for up to 24 months.
