SKU: INSYR1ML31G10

Pack of 10 sterile single-use 1ml (100 units) disposable insulin syringes with an integrated 31G x 1/4" (6mm) ultra-fine needle. Individually heat-sealed pouches for clean, accurate laboratory dosing.

What's included

  • 10x Sterile 1ml (100 unit) insulin syringes with fixed 31G x 1/4" (6mm) needles, each in its own heat-sealed pouch
Full product details

A pack of 10 disposable 1ml insulin syringes, each individually sealed in a sterile EO pouch. The 1ml barrel is graduated up to 100 units for precise micro-volume measurement, with a fixed 31G x 1/4" (6mm) ultra-fine needle for smooth, low-discomfort subcutaneous delivery.

Research

Insulin syringes are a staple of laboratory reconstitution workflows where small, accurate volumes need to be drawn directly from a vial. The 100-unit graduation on the 1ml barrel allows fine increments to be measured reliably, while the short 1/4" needle suits subcutaneous-style administration in controlled research settings.
