Insulin Syringes

1ml (31G) × 100 Insulin Syringes, for safe injection of peptides

Insulin Syringes

Insulin syringes are small, sterile medical devices specifically designed for subcutaneous injection of insulin in people with diabetes. They consist of three main parts: a barrel, plunger, and a short, fine needle.

Key Features

• Calibration in Units: Unlike regular syringes marked in milliliters (mL), insulin syringes are calibrated in insulin units (e.g., 30, 50, or 100 units), matching standard insulin concentrations like U-100 (100 units per mL).

• Syringe Sizes:

  • 0.3 mL (up to 30 units): For small doses

  • 0.5 mL (up to 50 units): For moderate doses

  • 1.0 mL (up to 100 units): For larger doses

• Needle Specifications:

  • Gauge: Typically 28G to 31G — higher numbers mean thinner needles, which reduce pain.

  • Length: Commonly 4 mm to 12.7 mm; shorter needles (4–6 mm) are preferred for most adults to avoid intramuscular injection.

Usage and Safety

• Single-use only: Always use a new, sterile syringe and needle to prevent infection, pain, and needle dulling.

• Proper disposal: Used syringes must be placed in a sharps container to prevent injury and contamination.

• Injection sites: Administered into fatty tissue on the abdomen, thigh, arm, or buttocks, with regular site rotation to prevent lipodystrophy.
