Stainless Steel Conjunction With Syringe Smaller-gauge Injection Needle

A hypodermic (hypo a under, dermic a the skin) needle is a hollow needle that is commonly used in conjunction with a syringe to inject substances into or extract fluids from the body. They can also be used to collect liquid samples from the body, such as blood from a vein during venipuncture. Intramuscular injections are administered directly into a muscle. Because muscle penetrates deeper than the skin, the needle used for these injections must be thicker and longer. Needles with a gauge of 20 or 22 G and a length of 1 or 1.5 inches are typically recommended. Only use the 3 mL and 5 mL syringes to dilute the Pfizer-BioNTech COVID-19 vaccine. For diluting, smaller-gauge needles (i.e., thicker) or blunt-tip needles should be used.
