What type of syringe used for small veins venipuncture?

For venipuncture in small veins, a small-volume syringe, typically a 1 mL or 3 mL syringe, is often used. These syringes allow for precise control and minimize trauma to the vein. Additionally, a butterfly needle or a smaller gauge needle (such as 23-25 gauge) is commonly employed to enhance access and reduce discomfort.
