Microliter syringes are for use with liquids only. They incorporate a hand-fitted stainless steel plunger with a finely bored syringe barrel. These syringes are ideal for homogeneous samples that are not prone to precipitation or bonding with glass.
Under the proper conditions, plunger wear is minimal and the life of a Microliter syringe is almost unlimited. However, when using heterogeneous solutions with a Microliter syringe, the user must be especially diligent about cleaning the syringe after each use. For more information, see our Hamilton Syringe Care and Use Guide on properly maintaining our syringes.
In some cases, even diligent cleaning is not sufficient and the barrel will become soiled. The deposits on the glass will compromise the tight tolerances between the glass and the plunger resulting in a frozen plunger. Plungers for Hamilton Microliter syringes cannot be interchanged or replaced if damaged. For heterogeneous solutions, a gas tight syringe is the best option.

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.
What is the volume range of the Microliter syringes?Microliter syringes accurately dispense volumes between 0.05 µL to 500 µL. These syringes feature a stainless-steel plunger individually fitted to the glass barrel, creating a liquid-tight seal and nearly frictionless movement. Hamilton Microliter Syringes include 600 Series, 700 Series, 800 Series, and 7000 Series syringes.
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.
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.
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.Talk to an engineer
