Gas Tight Syringes

Gastight syringes are ideal for dispensing both liquids and gases. They have a precision-machined PTFE plunger tip which creates a leak-free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.

Reference Guide - Laboratory Syringes and Needles
The Syringe and Needle Reference Guide provides detailed information on Hamilton Company’s full portfolio of syringes and needles. Everything from cleaning and preventative maintenance to individual part numbers are available for review. It also includes selection charts to help you choose between syringe terminations like cemented needles and luer tips. -
Technical Note - Determining Hamilton Syringe Performance
A general procedure based on determining the mass of deionized water samples delivered by a syringe. True volume is calculated based on the density of water at specific temperatures.

What is the difference between Gastight and Microliter syringes?
Microliter syringes feature an individually fitted, stainless-steel plunger creating a liquid-tight seal and nearly frictionless movement to accurately dispense liquids from 0.05 µL to 500 µL. Gastight syringes feature a precision-machined PTFE plunger tip creating a leak-free seal to dispense both liquids and gases from 1 µL to 2 L. -
What is the difference between a Syringe and a Calibrated Syringe?
These syringes are manufactured the exact same way. The Calibrated Syringe is a serialized syringe including a Certificate of Calibration traceable to NIST, whereas the Syringe does not include a certificate. Hamilton Company offers a recalibration service for Calibrated Syringes. All Calibrated Syringe part numbers begin with CAL.

Syringe Terminations
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.

Work with R&D engineers to customize Hamilton parts
Hamilton's "Custom Built" program puts you directly in contact with a Hamilton R&D Engineer to discuss your application and product needs. The engineer will point you to a standard solution or propose a customized solution to meet your needs.
