View Hamilton's needle gauge chart. Hamilton's guide to selecting a syringe needle gauge will help you find the proper Hamilton needles. Select the minimum needle length that allows you to carry out your application comfortably.
Below, you will learn the recommended needle gauges for different types of injections and get an overview of available needle gauges with their corresponding colors, outer diameters, and uses (+ downloadable size chart).
Needles are available in a range of sizes, from the thinnest (typically around 30 gauge) to the thickest (usually around 13 gauge). The size of the needle you should use for any particular task depends on the material you are using and the desired effect.
The gauge (abbreviated as “G”) of a needle refers to the size of the hole in the needle. The higher the gauge, the smaller the hole. Needles come in various gauges and lengths. The length of a needle is listed after the gauge number. For example, 25G 1⁄2 refers to a 25 gauge, 1⁄2 inch-long needle.
Needle gauges represent the size of the needle. They are available in standard sizes, coded colors, and varying in length. The LARGER the gauge number, the SMALLER the needle shaft. A 22 gauge needle has a smaller shaft than a 14 gauge needle. Needle Gauge Chart.
Overview. Hypodermic needles are available in a wide variety of outer diameters described by gauge numbers. Smaller gauge numbers indicate larger outer diameters. Inner diameter depends on both gauge and wall thickness. The following chart shows nominal inner diameter and wall thickness for regular-wall needles.
Here is a general guide to Needle Gauge sizes and their recommended uses: 18-20 gauge: Used for blood transfusions, anesthesia, and surgery. 21-23 gauge: Used for blood draws, vaccinations, and medication injections. 24-26 gauge: Used for insulin injections, pediatric patients, and subcutaneous injections.
Needle Gauge Size Chart. table: Needle gauge size. Find below the complete table of the inner and outer diameters of hypodermic needle gauges. Use it to determine the needle you should use.
Needle Gauge sizes are important in phlebotomy procedures for drawing blood accurately and efficiently. The most commonly used Needle Gauge sizes in the United States range from 18 to 25, with smaller numbers indicating larger needle diameters.
Below is a needle gauge chart showing the sizes of needles used for the Evacuated Tube System, Syringe Method, and the Butterfly Needle when performing venipuncture. Tables showing needle sizes for blood draws. The evacuated tube method is used for good and healthy veins found in the antecubital fossa area. Evacuated Tube System Needle Gauge Chart.
