Small Hub RN

The Small Hub Removable Needles (RN) design allows for needle replacement on RN syringes with a volume capacity of 100 µL or smaller. Users can select the gauge, point style, and length, with further customizations available. 

Needles Removable Needle Small Hub

Engineered for confident small-volume injections

Small Hub Removable Needles (RN) combine precision and adaptability for laboratory injection applications. Compatible with Removable Needle (RN) syringes 100 µL or smaller, the ability to swap needles extends syringe utility and allows replacement of bent or damaged needles. The hub aligns with the zero line on the syringe barrel for minimized dead volume which ensures high injection accuracy and precision. Small Hub Removable Needles include six needles per pack, and are available in a wide range of gauge, length, and point style combinations to choose from.  

What you can expect

  • Enhance laboratory injection efficiency

    Replace damaged needles or adapt to different uses with removable needles to minimize costs and enhance flexibility.

  • Consistent, reliable needle performance

    The small hub RN precisely aligns with the syringe’s zero line for maximum accuracy and precision with minimal sample loss.

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.
