1800 Series Gastight™ Removable-Needle Syringes

Attached to the flange of the syringe is a blue Syringe Holder. The Syringe Holder provides a spot to hold the syringe that will not heat up the barrel causing dispense inaccuracies. Additionally it provides support to small volume plungers that are prone to bending during injection. A variety of different terminations and needle options are available.

1800 Series Syringe Terminations

• Removable Needle (RN)- The needles are removable and are a Hamilton-specific design. The design allows the needles to seat precisely at the zero graduation mark of the syringe. Users can select the needle gauge, length, and point style to optimize the syringe for custom applications. Additionally, this termination allows for a removable needle without increasing the dead volume of the syringe and is ideal when there is a risk of the needle clogging. Autoclavable when disassembled. Repeated autoclaving will shorten syringe life.

• Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting. Available gauges: 22
• Point Style 4 - Standard 12° beveled needle point is recommended for life science applications. Available gauges: 22. Special point styles such as 30°, 45°, or any other angle are available upon request.
• Point Style 5 - Conical needle with side port for penetration of septa, thin-gauged vinyls and plastics without coring. Available gauges: 26-22
