20 Syringe Size 3 ml 23G

20 Syringe Size 3 ml 23G Unlike standard measurement systems, there is an inverse relationship for the gauge numbers and the size of needles. As the gauge number increases, the needle width gets narrower. For example, a 22g needle is thinner than a 21g. This difference is critical to remember, as there is no uniform gauge size for all phlebotomist patients. Each needle varies in their blood flow rate and compatibility with specific vein types.

Although 21, 22, and 23 gauge needles are three of the most common needles, a broad knowledge of all needle types is beneficial to accommodate the different sizes of veins and tissues the phlebotomist may come across.
