Lab needles need to perform in many different environments and terminations are available in non-coring, beveled, drilled side port and more. Click to see which version is best for your application.
Needle Gauge Index
In addition to being inert stainless steel, lab needles require proper sizing in order to function properly. The diameter of a needle is defined by its gauge. In addition to being inert stainless steel, lab needles require proper sizing in order to function properly. Hamilton company offers a wide spectrum of gauges. This index displays the internal and outer dimensions as well as the dead volume.
Needle Length Guide
Needle length is a critical consideration for every application. Each needle hub design requires a slightly different length definition. It doesn't matter if the application is utilizing lab needles for life science injection or environmental analysis of ground water, the injection needs to hit the right target. This guide illustrates how to make the different measurements.
