Why Apex
Quality you can document.
We built Apex around the part most suppliers skip: proof. Every compound is traceable to a lot, and every lot is traceable to an independent report.
Independent assay
Every lot is HPLC and MS assayed by an outside laboratory before it is released for sale.
Purity standard
We hold a 99%+ purity threshold. Anything that fails the spec never reaches the catalog.
Full documentation
Lot-matched certificates of analysis are available on request for any item you order.
Research focus
Materials are supplied strictly for in-vitro laboratory research by qualified personnel.
