## FAQ

### Why is low dead space important in a peptide pen?

Low dead space means less of your reconstituted peptide solution gets trapped inside the needle and mechanism after use. This ensures the concentration you calculate is accurate and prevents wasting expensive sample.

### Can I use any syringe for peptide reconstitution?

While you can, a specialized reusable pen offers superior control for slow diluent addition, minimized dead space, and is made of sterilizable materials like glass and steel.

### How do I clean a reusable peptide pen?

After each use, flush the system with sterile water. For full sterilization, disassemble the components (if possible) and autoclave them according to the manufacturer's instructions. Always replace the needle.
