Machine-readable facts for this Lab article. The full page is https://www.preppinpeppers.com/blogs/the-lab/peptide-pen-dead-volume-are-you-wasting-100-of-your-vial.
TL;DR
Dead volume is the reconstituted liquid trapped in the needle and cartridge tip after a draw. Metal pens like the Gansulin have less of it than plastic pens.

FAQ
- What is dead volume in a peptide pen cartridge?
- Dead volume is the small amount of reconstituted peptide solution that remains trapped in the needle hub and fluid path after the plunger is fully depressed, and it cannot be dispensed.
- How much peptide solution is lost per use with a typical glass cartridge?
- A typical 3ml glass cartridge has a dead volume of 0.03 to 0.05 ml per draw. This means that much volume is lost each time a dose is dispensed from the pen.
- Should I store my reconstituted peptide in the pen cartridge?
- The pen cartridge is not ideal for long-term storage. For research stability, aliquot your reconstituted peptide into low-binding tubes and store them frozen.
