Definitions and Terminology

One of the first steps to understanding the ideal syringe for your specific application is to know which termination is best. This article helps you make that determination, explaining what to choose based on your requirements like dispense volume, need for autoclaving, desired dead volume, pressure tolerances, or necessary headspace.

Hamilton manufactures a variety of plungers depending on the intended use of the syringe. This article describes which plunger design and materials are optimal for each type of syringe.

Another aspect of proper syringe selection requires knowing the graduations visible on a particular syringe series and volume. This detailed table of data provides scale length, total scale divisions, major graduations, minor graduations, and sub-minor graduations of each syringe series by volume.

Hamilton offers a variety of different laboratory needle point designs. Needle termination selection is very important to the proper function of an application. Lab needles need to perform in many different environments. Terminations are available in non-coring, beveled, drilled side port and more.

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. Hamilton company offers a wide spectrum of gauges. This index displays the internal and outer dimensions and the dead volume.

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.
