FAQ
- What makes a peptide pen more accurate than a syringe?
- A quality pen uses a click-dial metering mechanism with consistent increments and a tight-tolerance metal body, reducing parallax error and volume variation compared to manually reading a syringe barrel.
- Can I use the same peptide pen for different diluents?
- Yes, but you must thoroughly flush the mechanism with sterile water between different diluents to prevent cross-contamination that could affect your sample chemistry.
- How do I choose between bacteriostatic water and sterile water for reconstitution?
- Choose bacteriostatic water for samples needing multiple withdrawals over time due to its preservative. Choose sterile water for single-use, endotoxin-sensitive applications where purity is paramount.
