Hypodermic Needles

Overview

Hypodermic needles in gauges 18G–30G with ISO hub colour coding. Compatible with TTT World syringe range. A hypodermic needle is a manually operated medical device used in conjunction with a syringe to inject substances (such as medications or solutions) into the body or to withdraw fluids (such as blood). It is a subcutaneous needle that penetrates the skin and is typically designed as a sharp, hollow metal tube . Hypodermic needles vary in bevel shape, gauge, diameter, and length , depending on their intended use. They are commonly used for rapid fluid administration , when oral intake is not possible (e.g., vomiting), or when drugs (like insulin) require subcutaneous absorption. They are also critical in research environments that require strict sterile conditions , such as during the inoculation of sterile substrates, significantly reducing the risk of contamination. Why Hypodermic Needles Minimize Contamination: The needle surface is extremely smooth , preventing airborne pathogens from adhering and transferring to the substrate. The needle tip is exceptionally sharp , leaving a very small puncture , which reduces the chance of larger microorganisms contaminating the entry point. Hypodermic needles are usually high-grade stainless steel , with beveled and sharpened tips for smooth, painless skin penetration .
