Insulin Syringes 10-Pack

These U-100 insulin syringes (1ml, 29 gauge) are the practical standard for subcutaneous peptide administration in animal research protocols. The U-100 graduation means 1 unit = 10 mcg for a 1mg/ml solution -- a graduation scale that maps intuitively onto common peptide dosing ranges. The 29 gauge needle minimizes tissue trauma at the injection site, which matters in repeated-injection protocols where site reactions can confound results or cause animal distress.

Why Insulin Syringes for Peptide Research

Standard laboratory syringes in the 1-5ml range have too coarse a graduation for the volumes involved in peptide dosing -- the typical 50-500 mcg dose requires accurate delivery of 0.05-0.5ml, and a 5ml syringe has 0.2ml graduations that make this impractical. Insulin syringes solve this with 0.01ml graduations (for U-100). The short needle (1/2 inch) is appropriate for subcutaneous injection in rodents and the fixed needle design eliminates the dead-space variability of Luer-lock connections, where 0.05-0.1ml can be lost in the hub.

For intraperitoneal injection in rodents, the same syringes work with slightly different angle technique. For intravenous injection, longer needle versions (5/8 inch) are preferred for tail vein access, but the 1/2 inch models work for retroorbital or cardiac approaches. The pack of 10 is sized for protocol optimization runs where you need enough to establish technique and dosing without committing to bulk purchase.

Storage

Store at room temperature in original packaging, away from heat and direct sunlight. Each syringe is individually sterile-packaged with an expiry date. Do not use after the printed date. In rodent research, each syringe should be used for a single animal and discarded -- reuse between animals introduces cross-contamination risk and dulls the needle enough to increase injection discomfort.

Insulin syringes are supplied for laboratory research use only. For research purposes only.
