Machined aluminium injector, graduated delivery
A reusable pen injector built for laboratories that want repeatable, graduated delivery instead of drawing by syringe every time. Machined aluminium body, brushed steel collar, no branding beyond the mark. Buy it once, it is not tied to any single compound.
Shipped with every compound order or on its own. Browse compounds.
The Instrument
Most delivery hardware is disposable, and it feels it. This is the opposite argument: one machined aluminium body, a brushed steel collar, and a mark small enough that you have to look for it. It is designed to sit on a bench for years rather than be thrown away after a cycle.
The pen carries no compound name and no dose. It is an instrument, not a product line, you decide what goes in it and at what concentration, exactly as you would with a syringe.

In The Box
The pen ships ready to run. Load your reconstituted compound and go, no separate order for the essentials.
Good To Know
No. The pen ships empty. Every ONE% compound is supplied as a lyophilised vial and reconstituted in the lab to the concentration your protocol requires; the pen is simply the delivery instrument you load afterwards.
Yes. It is not tied to a compound, a dose or a category, that is the point of buying it once. Any of our reconstituted compounds can be loaded into it.
The body is machined aluminium and wipes down with isopropyl. Follow your own laboratory's validated cleaning and handling procedure between uses.
No, a Certificate of Analysis describes the purity of a compound, not hardware. Every ONE% compound still ships with its own COA. How we test.
