Hamilton Glass Syringes are the Standard in Precision Measurement
Top quality materials and skilled workmanship ensure Hamilton syringes consistently deliver the highest possible performance for reliable analyses. Choose from more than 2,000 chemistry syringes and accessory part numbers or work with us to custom-build your own.
Hamilton continuously researches new materials and methods to improve the fit, form, and function of our borosilicate glass syringe and needle configurations. Our syringe catalog includes options for luer slip tips, nickel-plated brass luer lock terminations, and even heat-resistant 200°C Headspace Syringes. See other laboratory products here.
Needles for Laboratory Syringes
To choose the best needle, it is important to understand your syringe termination. The most common terminations are PTFE Luer Lock, Luer Tip, or Removable Needle.

Glass Syringe Care and Use
Reference Guide - Laboratory Syringes and Needles
Syringe Care and Use GuideHamilton’s Syringe Care and Use guide outlines the basics of daily syringe use and operation so that scientists and technicians can achieve the highest level of accuracy and precision. Important topics covered include inspection, operating temperature, trapped air, and sample carryover.
Instructions - Pipette ControllerThe pipette controller syringe is a Hamilton Gastight® Luer Tip syringe modified with a special free-sliding, thumb-wheel plunger. The syringe is supplied with 41 mm (1-5⁄8”) of clear vinyl tubing, 3 mm ID (0.125”) x 6 mm OD (0.250”), to attach a pipette to the syringe’s luer tip. The syringe draws liquids into the pipette (liquids do not enter the syringe barrel).
Instructions - Hamilton SaltLine SyringesSaltLine syringes were developed to combat the rigors of solutions with high salt concentrations.
I have a syringe, what's the part number?
What does the s mean in a 22s or 26s gauge needle?The "s" represents a smaller inner diameter for the needle and a thicker needle wall for better durability. For example, a 26 gauge needle has an outer diameter of 0.46 mm and an inner diameter of 0.26 mm while the 26s gauge needle has an outer diameter of 0.47 mm and an inner diameter of 0.13 mm. The 26s has half the inner diameter of the 26 gauge needle. The difference in the wall thickness also nearly doubled with 26s gauge having a thickness of 0.18 mm while the 26 gauge is only 0.10 mm.
I have a syringe, which needle do I need?If you already have a syringe and need a Hamilton needle, you can determine the appropriate needle if you know one of the following: 1) the glass syringe termination; 2) the glass syringe part number; or whether you are dealing with a common plastic syringe. Click the heading to learn more.
What is the accuracy of Hamilton syringes?Hamilton syringes are manufactured to be accurate within ±1% of nominal volume, and with precision within 1%, measured at 80% of total scale volume. The design of our barrel and plunger dimensions assures high levels of accuracy and precision. The Hamilton Company Quality System is ISO 9001: 2015 certified.
Syringe Knowledge Base
Syringe sterilization and disinfecting guideAre you curious whether your Hamilton syringe can be sterilized and disinfected via ethylene oxide, autoclavation, or chemical disinfectants? Consult this table of syringe terminations, syringe needles, and tubing types to learn the possible ways to sterilize and disinfect you Hamilton syringe.
Syringe TerminationsOne 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.
Syringe GraduationsAnother 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.
