Hamilton 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 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.
Needles for Syringes
To choose the best needle, it is important understand your syringe termination. The most common terminations are Kel F and metal luer lock tips.

Syringes for Higher Education
For over 60 years Hamilton has been committed to supporting academic research and innovation with syringe grants and special discounts. Help your grant money stretch further.
What is a Hamilton Syringe Product Grant?
Hamilton Company proudly supports higher education by awarding up to five $1,000 Syringe Product Grants each month to teaching facilities that use Hamilton syringes or needles as educational guides. In addition to $1,000 worth of Hamilton syringes you will also receive our Syringe Care and Use Guide to be used as an educational guide.
Hamilton Values Higher Education
Hamilton is committed to higher education and believes in the importance of developing the next generation of scientists. Learn how you can save 25% on all syringes, needles, and HPLC columns purchased throughout the year.
Work with Engineers to Customize Hamilton Syringes
The 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 syringe or propose a customized solution to meet your needs.
Reference Guide - Syringes and Needles
Guide - Syringe Care and UseHamilton’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.
Guide - Syringe SelectionThe key to selecting the right syringe for your application is to identify your sample type and determine the smallest volume to be dispensed or injected. Hamilton’s Syringe Selection Guide offers a step-by-step process and selection worksheet so that anyone involved in choosing a manual syringe understands all the configuration options, including syringe type, syringe series, volume, syringe termination, and needle point style.
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).
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 9001-2008 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 help 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.
