Confused About Choosing a Syringe? Here's the Difference Between Onemed Disposable Needle 18G to 30G!

In the medical world, choosing the right syringe is very important for patient comfort and the effectiveness of medical procedures. Onemed provides various sizes of disposable needles with various gauges (G), which determine their thickness and function. Here are the differences in each size of the Onemed Disposable Needle from 18G to 30G so you can choose according to your needs.

What is Gauge (G) on a Syringe?

Gauge (G) is the measurement of the outer diameter of the syringe needle. The larger the gauge number, the smaller the needle diameter. Conversely, the smaller the gauge number, the larger and thicker the needle.
