PetTest U-40 Syringes, 31 Gauge x 5/16-in are some of the thinnest, featuring 31-gauge needles. This helps make injection more comfortable for your furry family member compared to thicker 29-gauge U-40 needles. The length of the 5/16” needle also helps reduce the risk of a painful injection to your pet’s muscle. These syringes are specifically designed to be used with all U-40 insulins. Both sizes, the 0.3-cc and 0.5-cc have easy-to-read ½ unit marking for accurate dosing every time. The needles are extra sharp and lubricated and have a tri-bevel tip for added comfort, while the extra-wide finger grips allow for unmatched control. These syringes come with protective needle and plunger caps.


Syringes are primarily used to administer insulin to dogs, cats, and other animals.


Used sharps should be immediately placed in a sharps disposal container. FDA-cleared sharps containers are generally available through pharmacies, medical supply companies, health care providers and online. These containers are made of puncture-resistant plastic with leak-resistant sides and bottom. They also have a tight fitting, puncture-resistant lid. If an FDA-cleared container is not available a heavy-duty plastic household container, such as a laundry detergent container can be used as an alternative. For patients who mix two types of insulin, do not change (a) the order of mixing that the physician has prescribed or (b) the model and brand of the syringe without first consulting your physician or pharmacist. Failure to heed this warning can result in dosage error
