Dead space
The small volume of liquid that remains in the syringe hub and needle after the plunger is fully depressed. Can waste 0.02–0.07 mL of peptide per injection. Low dead-space syringes minimize this loss.
Frequently Asked Questions
What is Dead space?
The small volume of liquid that remains in the syringe hub and needle after the plunger is fully depressed. Can waste 0.02–0.07 mL of peptide per injection. Low dead-space syringes minimize this loss.
Why is Dead space important in peptide research?
Dead space relates to the tools and quality standards that ensure peptide safety and efficacy. Proper equipment and testing are critical for accurate dosing, contamination prevention, and verifying peptide authenticity.

Insulin syringe
A small-volume syringe (typically 0.3mL, 0.5mL, or 1mL) with a fixed fine-gauge needle, originally designed for insulin but widely used for subcutaneous peptide injections. Marked in units (100 units = 1 mL).
Syringe unitsMeasurement markings on insulin syringes, where 100 units = 1 mL. Understanding syringe units is essential for accurate peptide dosing after reconstitution.
