0.5mL | 28G x 1/2" - BD Micro-Fine™ IV Lo-Dose™ Insulin Syringe
Primo for injecting strictly sub-q or shallow IM!
A BD 28 gauge low dead space insulin syringe with a permanently attached microfine thin wall needle will have a flow rate equivalent to a standard wall 27 gauge insulin syringe with a permanently attached needle.
These were my go to syringes when I started T back in 2016.
Have also used 27-31G various needle lengths but prefer these as they are quick for drawing/injecting the oily solution even when cottonseed oil is the carrier.
Tried numerous brands over the years and always come back to BD top notch quality product!
- Using a BD thin-wall needle may enable you to use a smaller gauge needle as the flow rate is similar to a BD regular-wall needle one gauge larger
Selecting the Devices
There are many different syringes and needles, suiting many different procedures. It is important to choose the needles and syringes carefully according to the type of injection to be administered. For example, the length and gauge of the needle and type of syringe must be suitable for the injection site, viscosity, and volume of medication. The size, age, and condition of the patient are other key factors in the selection process.

Needle
Made of stainless steel, which is siliconized to allow easier penetration, thus minimizing patient discomfort. Available in different lengths and gauges to suit individual clinical and patient needs.
There are three types of needle walls:
Regular Wall: This is the most common wall thickness. The thickness of the steel wall allows a good flow rate and minimizes flexing when the needle is inserted into a vial stopper or patient.
Thin Wall: As shown in the diagram, the thin wall needle has a narrower steel wall, allowing a greater volume of fluid to pass through it. The flow rate is typically equivalent to that of a needle one gauge larger. This is especially important with very thin needles.
Extra Thin Wall: This has the thinnest steel wall, provides higher flow, and requires less force to deliver medication.
