Venting Needles

Venting Needles enable pressure equalization when aspirating or dispensing larger volumes from or into a closed container. These durable needles are ideal for piercing applications and ensure accurate and repeatable liquid transfer.

Reliable venting starts with Hamilton

Trust in Hamilton venting needles to facilitate pressure equalization with sealed systems and closed containers. These high-quality stainless steel venting needles feature high corrosion resistance and reduce the risk of cross contamination.  With various needle hubs, gauges, lengths, and point style configurations available, users can select from our off-the-shelf options or select custom specifications.   

  • The Hamilton venting needles allow performing precise dosing of solutions.

    In automation, sealed vials present problems with positive/negative pressure when trying to aspirate and dispense liquids. The Hamilton venting needles allowed us to perform precise dosing of solutions and solvents in crimp capped GC vials. The ratio of dispensing was critical for the final sample prior to HPLC analysis.

Needle Gauge Chart

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 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.
