FAQ
- What cartridges are compatible with the Gansulin metal reusable pen?
- The Gansulin metal pen is designed for standard 3 mL glass cartridges. Most reconstitution volume calculations are built around that size, so the math aligns conveniently with typical laboratory workflows.
- Why is bacteriostatic water used for reconstitution instead of regular water?
- Bacteriostatic water contains a small amount of benzyl alcohol, which inhibits bacterial growth and keeps the reconstituted solution stable during laboratory storage — making it the standard choice for research reconstitution.
- How do I determine the correct draw volume when using the Gansulin pen?
- Use a peptide calculator to compute your solution's concentration based on the powder amount and liquid volume added, then dial that exact draw volume on the pen before each use.
