Reusable devices

Refillable peptide pens

Durable, precision pen devices your lab keeps between studies — reload a fresh cartridge for each compound. Precise measurement, less waste, and the same consistent format across every Peptiva compound.

One device, every compound

A single reusable pen works across the full Peptiva range — swap the cartridge, keep the device.

Precise, repeatable measurement

A calibrated dial for consistent handling at the bench — no syringe math.

Less waste, lower cost

Reload cartridges instead of replacing the whole unit — efficient for higher-volume labs.
