What does 32G needle mean?
You might think the higher the number, the thicker the needle, but it’s actually the opposite. The higher the number, the thinner the needle is. For example, 32G needles, like those available with NovoFine® Plus, NovoFine®, and NovoTwist®, are thinner than a 27G needle.
Which is thinner 31G or 32G needles?
In a single center and open label study, we investigated if this new and thinner 32G needle is superior to NovoFine 31G 6mm needle (diameter : 0.25mm; hereinafter 31G) which is one of the current mainstream needles. [br]Diabetic patients using 31G for insulin injection for more than 1 month (n=22) used 32G for 1 month.
What is a 30g needle used for?
Subcutaneous injection are well known for a the injection of insulin for people suffering with diabetes, again the chosen needle gauge ranges from 25g to 30g as they are the most efficient in delivering the liquid in between the skin and muscles.
Does the size of the syringe matter?
In conclusion, smaller needles can reduce pain and provide other advantages that can increase patient compliance. Fine needles of 33–31 gauge have already gained clinical acceptance and still smaller microneedles are under development.
What size is a 32 gauge needle?

Does a 25G needle hurt?
63 patients were allocated to the 23G needle group and 56 to the 25G needle group. The mean pain score was 3.5 (SD=2.7) for the 23G group and 3.4 (SD=2.7) for the 25G group with a mean difference between the pain scores of 0.1 (95% CI −0.9 to 1.1, p=0.83).
Which is bigger 28 gauge or 30 gauge?
For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle. Different companies use different measurements for gauges, so it is important to specify inner diameter….Plastic (Straight 0.25″, 0.5″, or 1.0″)
| Gauge Size | Inner Diameter (mm) | Color |
|---|---|---|
| 27 | 0.200 | Clear |
| 28 | 0.190 | Grey |
| 30* | 0.152 | Lavender |
| 32 | 0.100 | Yellow |
Is a 30 gauge needle painful?
Two types of disposable injection needles were tested clinically for pain of insertion, and penetration resistance. The 30-gauge needle required significantly less force (69 mN) than the 27-gauge needle (139 mN). The difference in pain perception was less remarkable.
What does 30g needle mean?
The gauge size of a needle indicates what the diameter of the lumen (opening) is. The higher the gauge, the smaller the diameter. For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle. Different companies use different measurements for gauges, so it is important to specify inner diameter.
